Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is a form of motion experienced by an object or particle that is thrown near the earth's surface and moves along a curved path under the action of gravity only.

Front

What are the two components of projectile motion?

Back

The two components are horizontal motion (v_x) and vertical motion (v_y).

Front

What is the acceleration in the horizontal direction of a projectile?

Back

The acceleration in the horizontal direction is 0 m/s² in the absence of air resistance.

Front

What is the acceleration in the vertical direction of a projectile?

Back

The acceleration in the vertical direction is -9.81 m/s² due to gravity.

Front

At what point is v_y = 0 m/s in projectile motion?

Back

At the highest point of the projectile's path.

Front

What is the velocity in the horizontal direction at the highest point of a projectile's path?

Back

The velocity in the horizontal direction remains constant and is equal to v_x.

Front

What angle provides the maximum range for a projectile?

Back

The angle that provides the maximum range is 45°.

Front

What happens to the vertical velocity of a projectile as it rises?

Back

The vertical velocity decreases until it reaches 0 m/s at the highest point.

Front

What happens to the vertical velocity of a projectile as it falls?

Back

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

Front

What is the range of a projectile?

Back

The range is the horizontal distance traveled by the projectile from launch to landing.
