Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path called a trajectory.

Front

What is the acceleration of a projectile in free fall?

Back

9.8 m/s², directed downward due to gravity.

Front

At what angle should a projectile be launched to achieve maximum range in the absence of air resistance?

Back

45°.

Front

What is the direction of the acceleration of a projectile?

Back

Downward, towards the center of the Earth.

Front

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

Back

The vertical velocity is zero at the highest point.

Front

What is the horizontal velocity of a projectile during its flight?

Back

The horizontal velocity remains constant if air resistance is negligible.

Front

If two objects are dropped from the same height, will they hit the ground at the same time?

Back

Yes, they will hit the ground at the same time regardless of their horizontal velocities.

Front

What is the formula for the range of a projectile launched at an angle θ with initial velocity v₀?

Back

Range = (v₀² * sin(2θ)) / g, where g is the acceleration due to gravity.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance reduces the range and alters the trajectory of the projectile.

Front

How does the initial vertical velocity affect the time of flight of a projectile?

Back

Greater initial vertical velocity results in a longer time of flight.
