• gravity

• speed

force that results from the interaction of two objects in contact with each other

• noncontact force

• speed

• velocity

• contact force

force that occurs without objects touching

• energy transfer

• gravity

• contact force

• noncontact force

a noncontact force that acts over a distance and pulls all objects toward each other

• speed

• velocity

• acceleration

• gravity

the movement of energy from one object to another or the change of energy from one form to another

• gravity
