Gravity and Friction

What is the meaning of Force?

• •Force is defined as a push or a pull acting on an object

• Force is defined as a push acting on an object.

• Force is defined as a pull acting on an object.

• Force is defined as not pushing or pulling on an object.

A force usually results from an interaction

• True

• False

Forces resulting from physical interaction are called ' Non-Contact Forces'

• True

• False

Gravity is a type of...

• Non-contact Force

• Contact force

It is the_______________ that keep everything at its place. Otherwise, we would have been floating in the air.

Weight is...

• Is the amount of matter in an object.

• Is the measure of the pull of gravity on that mass

• Is a force that slows down moving objects, or prevents an object in rest to move

• All of the above

•The more mass an object has, the__________ its gravitational force.

•The farther apart two objects are, the_________ the gravitational force between them.

Friction means...

• is a force that slows down moving objects, or prevents an object in rest to move.

• Is a force that pulls things downward.

• It is the force that keep everything at its place. Otherwise, we would have been floating in the air.

• Is the amount of matter in an object

When something falls, air resistance acts in the opposite direction as the force of gravity.

• True

• False
