In referring to how much matter a body contains, we use the term:

Back

Mass.

Front

Which type of force(s) will cause a change in an object's motion?

Back

Unbalanced forces.

Front

What is Newton's First Law?

Back

An object at rest stays at rest, and an object in motion stays in motion.

Front

A 20 kg bike accelerates at 10 m/s². What was the force?

Back

200 Newtons.

Front

What is the formula for calculating force?

Back

F = ma (Force = mass × acceleration).

Front

What does inertia refer to in Newton's First Law?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).

Front

What is an example of balanced forces?

Back

Two people pushing a car with equal force in opposite directions.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate or change its motion.
