Bell work #4

Front

What is inertia?

Back

The resistance of any physical object to any change in its state of motion or rest.

Front

What is a force?

Back

A push or pull that can cause an object to accelerate.

Front

True or False: A truck has more inertia than a bicycle.

Back

True

Front

Which requires more force to throw: a bowling ball or a basketball?

Back

The bowling ball has a greater mass, so it will take more force.

Front

What does Newton's 1st law state?

Back

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

Front

What does Newton's 2nd law state?

Back

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

Front

What does Newton's 3rd law state?

Back

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

Front

What unit is used to measure force?

Back

Newton (N).

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is acceleration?

Back

The rate of change of velocity of an object.
