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 and vertical motion. They are independent of each other.

Front

What is the acceleration of an object in projectile motion?

Back

The acceleration is constant and equal to the acceleration due to gravity, approximately 9.81 m/s² downward.

Front

What happens to the vertical velocity of a projectile at its highest point?

Back

At its highest point, the vertical velocity (v_y) is 0 m/s.

Front

How does the horizontal velocity of a projectile change during its flight?

Back

The horizontal velocity remains constant throughout the flight, assuming no air resistance.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory.

Front

If an object is thrown straight up, what is its velocity at the peak?

Back

The velocity at the peak is zero.

Front

How long does it take for a projectile to rise to its peak compared to the time it takes to fall back down?

Back

The time to rise to the peak is equal to the time to fall back down.

Front

What is the range of a projectile?

Back

The range is the horizontal distance traveled by the projectile before it hits the ground.

Front

What factors affect the range of a projectile?

Back

The range is affected by the initial velocity, launch angle, and height of launch.
