What is the formula to calculate speed?

Back

Speed = distance/time

Front

What is the acceleration of objects falling on Earth due to gravity?

Back

9.8 m/s²

Front

What can be measured in meters per second (m/s)?

Back

Speed

If a girl drops a 7 gram bowling ball and a 1 gram rock from a cliff, which will hit the ground first?

Back

Ignoring air resistance, both will hit at the same time.

Front

A ball drops from a tall building. The ball strikes the sidewalk 2.0 seconds later. What is the speed of the ball when it hits the sidewalk?

Back

20 m/s

Front

What is the unit of acceleration due to gravity?

Back

m/s²

Front

What is the effect of air resistance on falling objects?

Back

It slows down the objects, causing them to fall at different rates.

Front

What is the relationship between mass and acceleration due to gravity?

Back

Mass does not affect the acceleration due to gravity; all objects fall at the same rate in a vacuum.

Front

What is free fall?

Back

The motion of an object falling solely under the influence of gravity.

Front

What is the value of gravitational acceleration on the Moon?

Back

Approximately 1.6 m/s².
