0.36 m/s².

Front

Which of Newton's laws is shown when a magician pulls a tablecloth out from under the dishes?

Back

First law.

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 an unbalanced force.

Front

What is Newton's second 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 × acceleration.

Front

What is inertia?

Back

The tendency of an object to resist any change in its motion.

Front

What is an example of action and reaction?

Back
