# Mini-Quiz: Effect of Gravity on Sideways Motion

by Ron Kurtus (updated 29 May 2023)

Take this Mini-Quiz to check your understanding of the lesson material.

1. Why doesn't gravity affect an object moving sideways differently?

Gravity pulls perpendicular to the ground, so sideways motion is not affected

Sideways motion is too fast for gravity to affect it

Gravity pulls sideways motion faster than stationary motion

2. After 2 seconds, which object is falling downward faster?

The stationary object falls faster because gravity affects it more

The object moving sideways falls downward faster because of less friction

They both are moving at the same downward velocity after 2 seconds

3. If two balls are thrown sideways at different velocities, will they hit the ground at the same time?

Yes, because sideways velocities do not affect the rate the balls fall

No, because the harder you throw a ball, the less gravity affects it

It depends whether the balls are the same weight or not

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
