Front

What is normal force?

Back

Front

What is tension?

Back

Tension is the force that is transmitted through a string, rope, or wire when it is pulled tight by forces acting from opposite ends.

Front

What is the relationship between mass and force?

Front

What happens when two surfaces slide against each other?

Back
