Front

Give an example of Newton's Law of Inertia.

Back

When a car stops suddenly, passengers lurch forward due to inertia.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What happens to your mass and weight on Mars?

Back

Your mass remains the same, but your weight is less due to lower gravity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another object.

Front

What is the net force in a tug of war?

Back

The net force is the difference between the forces exerted by each side.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravity.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.
