Which Of The Following Are Correct Attributes Of The Vertical Component Of Projectile Motion?Select All That Apply.- Zero Velocity- Zero Acceleration- Constant Force- Constant Velocity- Constant Acceleration- Zero Force
Projectile motion is a fundamental concept in physics that describes the motion of an object under the influence of gravity. When an object is projected into the air, it experiences both horizontal and vertical components of motion. In this article, we will focus on the vertical component of projectile motion and identify the correct attributes that apply to it.
The Vertical Component of Projectile Motion
The vertical component of projectile motion is the motion of an object in the vertical direction, which is influenced by the force of gravity. When an object is projected upwards, it experiences a downward acceleration due to gravity, which slows it down and eventually brings it back to the ground. On the other hand, when an object is projected downwards, it experiences an upward acceleration due to gravity, which slows it down and eventually brings it to a stop.
Attributes of the Vertical Component of Projectile Motion
The vertical component of projectile motion has several attributes that are essential to understand. Let's examine each of the options provided and determine which ones are correct.
Zero Velocity
- Is zero velocity a correct attribute of the vertical component of projectile motion?
- No, zero velocity is not a correct attribute of the vertical component of projectile motion. At the peak of its trajectory, the vertical velocity of an object is zero, but this is a temporary condition. As the object begins to fall, its velocity increases, and it eventually reaches a maximum velocity before slowing down due to air resistance.
Zero Acceleration
- Is zero acceleration a correct attribute of the vertical component of projectile motion?
- No, zero acceleration is not a correct attribute of the vertical component of projectile motion. The vertical component of an object's motion is always under the influence of gravity, which means it is always accelerating. The acceleration due to gravity is a constant 9.8 m/s^2 on Earth's surface.
Constant Force
- Is constant force a correct attribute of the vertical component of projectile motion?
- Yes, constant force is a correct attribute of the vertical component of projectile motion. The force of gravity acting on an object is a constant force that is always present, regardless of the object's velocity or position.
Constant Velocity
- Is constant velocity a correct attribute of the vertical component of projectile motion?
- No, constant velocity is not a correct attribute of the vertical component of projectile motion. The vertical velocity of an object changes constantly due to the acceleration caused by gravity.
Constant Acceleration
- Is constant acceleration a correct attribute of the vertical component of projectile motion?
- Yes, constant acceleration is a correct attribute of the vertical component of projectile motion. The acceleration due to gravity is a constant 9.8 m/s^2 on Earth's surface, which means that the vertical component of an object's motion is always accelerating at a constant rate.
Zero Force
- Is zero force a correct attribute of the vertical component of projectile motion?
- No, zero force is not a correct attribute of the vertical component of projectile motion. The force of gravity acting on an object is always present, regardless of the object's velocity or position.
Conclusion
In conclusion, the vertical component of projectile motion has several attributes that are essential to understand. The correct attributes of the vertical component of projectile motion are constant force and constant acceleration. Zero velocity, zero acceleration, constant velocity, and zero force are not correct attributes of the vertical component of projectile motion.

Projectile Motion Q&A =====================
Projectile motion is a fundamental concept in physics that describes the motion of an object under the influence of gravity. In this article, we will answer some frequently asked questions about projectile motion.
Q: What is projectile motion?
A: Projectile motion is the motion of an object under the influence of gravity. It is a type of motion that occurs when an object is projected into the air and follows a curved path under the influence of gravity.
Q: What are the two main components of projectile motion?
A: The two main components of projectile motion are the horizontal and vertical components. The horizontal component is the motion of the object in the horizontal direction, while the vertical component is the motion of the object in the vertical direction.
Q: What is the acceleration due to gravity?
A: The acceleration due to gravity is a constant 9.8 m/s^2 on Earth's surface. It is the acceleration that an object experiences due to the force of gravity.
Q: Is the force of gravity always present?
A: Yes, the force of gravity acting on an object is always present, regardless of the object's velocity or position.
Q: What is the difference between horizontal and vertical motion?
A: The horizontal motion of an object is not affected by gravity, while the vertical motion of an object is always under the influence of gravity. This means that the horizontal velocity of an object remains constant, while the vertical velocity of an object changes constantly due to the acceleration caused by gravity.
Q: What is the trajectory of a projectile?
A: The trajectory of a projectile is the path that the object follows as it moves under the influence of gravity. The trajectory is a parabola, which is a curved path that opens downwards.
Q: What are the factors that affect the trajectory of a projectile?
A: The factors that affect the trajectory of a projectile are the initial velocity, the angle of projection, and the acceleration due to gravity. The initial velocity determines the speed of the projectile, while the angle of projection determines the direction of the projectile. The acceleration due to gravity determines the shape of the trajectory.
Q: What is the range of a projectile?
A: The range of a projectile is the maximum horizontal distance that the object travels before it hits the ground. The range is determined by the initial velocity, the angle of projection, and the acceleration due to gravity.
Q: What is the maximum height of a projectile?
A: The maximum height of a projectile is the highest point that the object reaches before it starts to fall back down. The maximum height is determined by the initial velocity, the angle of projection, and the acceleration due to gravity.
Q: What is the time of flight of a projectile?
A: The time of flight of a projectile is the time that it takes for the object to travel from the point of projection to the point where it hits the ground. The time of flight is determined by the initial velocity, the angle of projection, and the acceleration due to gravity.
Q: What is the velocity of a projectile at the maximum height?
A: The velocity of a projectile at the maximum height is zero. This is because the vertical velocity of the object is zero at the maximum height, and the horizontal velocity remains constant throughout the motion.
Q: What is the acceleration of a projectile at the maximum height?
A: The acceleration of a projectile at the maximum height is zero. This is because the acceleration due to gravity is zero at the maximum height, and the object is momentarily at rest.
Q: What is the force acting on a projectile at the maximum height?
A: The force acting on a projectile at the maximum height is zero. This is because the force of gravity is zero at the maximum height, and the object is momentarily at rest.
Q: What is the energy of a projectile at the maximum height?
A: The energy of a projectile at the maximum height is the sum of its kinetic energy and potential energy. The kinetic energy is zero because the velocity of the object is zero, and the potential energy is maximum because the object is at its highest point.
Q: What is the momentum of a projectile at the maximum height?
A: The momentum of a projectile at the maximum height is zero. This is because the velocity of the object is zero, and the momentum is the product of the velocity and the mass of the object.
Conclusion
In conclusion, projectile motion is a fundamental concept in physics that describes the motion of an object under the influence of gravity. The two main components of projectile motion are the horizontal and vertical components, and the acceleration due to gravity is a constant 9.8 m/s^2 on Earth's surface.
