AP Physics Projectiles - 2D Motion (with Explanations)

Front

What is the velocity of a projectile at its highest point?

Back

0 m/s

Front

At what point in a projectile's motion is the vertical velocity (v_y) equal to 0 m/s?

Back

At the highest point of its trajectory.

Front

How do you calculate the horizontal component of a projectile's velocity?

Back

Use the formula: horizontal velocity = initial velocity × cos(angle).

Front

If a projectile is thrown straight up, what is its speed when caught at the same height?

Back

It is equal to the initial speed at which it was thrown.

Front

What is the formula to calculate the horizontal distance traveled by a projectile?

Back

Horizontal distance = horizontal velocity × time of flight.

Front

What factors affect the range of a projectile?

Back

Initial velocity, launch angle, and height of launch.

Front

What is the effect of air resistance on projectile motion?

Back

It reduces the range and alters the trajectory of the projectile.

Front

What is the acceleration of a projectile in the vertical direction during its flight?

Back

-9.8 m/s² (due to gravity).

Front

How does the launch angle affect the maximum height of a projectile?

Back

A higher launch angle increases the maximum height.

Front

What is the relationship between the time of flight and the launch angle of a projectile?

Back

Time of flight is maximized at a launch angle of 45 degrees.
