Front

What is the force exerted by a chair to support a man weighing 800 newtons?

Back

800 N

Front

Why does a person continue to fly forward in a car after a crash?

Back

The person is still in motion.

Front

What law states that an object in motion stays in motion and an object at rest stays at rest?

Back

Newton's 1st Law (Inertia)

Front

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

Back

Inertia

Front

What force causes an inflated balloon to move horizontally when released?

Back

Action-reaction force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What is inertia?

Back

Inertia is the property 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 x Gravity).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.
