Back

They will both strike the ground at the same time.

Front

True or False: Friction depends on how much the materials in contact are pushed together.

Back

Front

What forces are balanced when an object reaches its terminal speed?

Back

Weight and air resistance are balanced at terminal speed.

Front

What is the unit of pressure known as a pascal?

Back

Back

Front

What is the relationship between mass and weight?

Back

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by air resistance.

Front

Explain the concept of balanced forces.

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the formula for calculating pressure?
