Projectile Motion

Front

In the absence of air resistance, why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?

Back

No horizontal acceleration

Answer explanation

No acceleration means the velocity does not change. A constant acceleration means the velocity is changing by the same amount each second.

Front

How does the downward component of the motion of a projectile compare with the motion of free fall?

Back

Front

At the instant a ball is thrown horizontally with an initial velocity, a ball held at the same height is released from rest and drops to the ground. If we ignore air resistance, which ball hits the ground first?

Back

Same Time
