Question

__________ (friction/gravity) makes movement of heavy objects difficult.​

Answer 1

Friction makes movement of heavy objects difficult.​

Explanation:

• Friction is the force that occurs when one object rubs against another object.

• Frictional force makes it difficult to start a heavy object moving. Enough force must be applied to the non-moving object to overcome the frictional force between the object and the surface in contact.

Hence, Friction makes movement of heavy objects difficult.​

Answer 2

Answer:

friction makes movement possible
