Forces and motion

Front

What measures an object's tendency to resist changing its motion?

Back

Inertia

Front

How can you increase the acceleration of an object?

Back

Decrease its mass.

Front

What is the net force when all forces acting on an object are balanced?

Back

0 N.

Front

What happens in a game of tug-of-war when both teams pull the rope with equal force and in opposite directions?

Back

The rope does not move.

Front

What is the net force if there is a force of 400 N Down?

Back

400 N Down.

Front

What is the definition of force?

Back

A push or pull on an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration = Net Force / Mass.

Front

What is the relationship between mass and weight?

Back

Weight = Mass x Gravity.

Front

What is friction?

Back

A force that opposes motion between two surfaces in contact.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
