Front

How does the absence of friction affect a marble traveling on a straight path?

Back

The marble would remain at a constant speed.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is terminal velocity?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is gravitational force?

Back

The attractive force between two masses.

Front

What happens to an object's weight on the Moon compared to Earth?

Back

It decreases because the Moon's gravitational pull is weaker.
