Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components are horizontal motion (constant velocity) and vertical motion (accelerated motion due to gravity).

What is the acceleration due to gravity?

Back

Front

What happens to the horizontal velocity of a projectile?

Back

The horizontal velocity of a projectile remains constant if air resistance is negligible.

Front

What is the shape of the trajectory of a projectile?

Back

The trajectory of a projectile is a parabola.

Front

At what point is the vertical velocity of a projectile zero?

Back

The vertical velocity is zero at the peak of its trajectory.

Front

What is the effect of mass on the acceleration of a falling object?

Back

The acceleration of a falling object is independent of its mass; all objects fall at the same rate in a vacuum.

Front

How does the vertical velocity change as a projectile rises?

Back

The vertical velocity decreases as the projectile rises until it reaches its peak.

Front

How does the vertical velocity change as a projectile falls?

Back

The vertical velocity increases as the projectile falls due to the acceleration of gravity.

Front

What is vertical displacement in projectile motion?

Back

Vertical displacement is the change in height of the projectile from its starting point to its highest point or to the ground.
