Front

What happens to the pull of gravity as the product of two objects' masses increases?

Back

The pull of gravity increases.

Front

What is the unit called that measures force?

Back

Newton.

Front

What occurs when two teams pull with the same amount of force?

Back

They will not move at all.

Front

If a feather and a hammer are dropped at the same time on the moon, which one will hit the ground first?

Back

Front

What is gravity?

Back

A force that attracts two bodies towards each other.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is an unbalanced force?

Back

Forces that cause an object to accelerate.

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is the effect of gravity on objects in free fall?

Back

All objects accelerate downwards at the same rate regardless of their mass.
