Newtons First Law

Front

What are the two factors that affect the force of gravity between two objects?

Back

Mass and Distance

Front

True or False: A hockey puck sliding on a frictionless surface will eventually slow down due to its inertia.

Back

False

Front

What is the term for the tendency of an object to resist a change in motion?

Back

Inertia

Front

What is the unit of measurement for force?

Back

Newton

Front

If you push on a car and it does not move, what can be said about its inertia?

Back

The inertia of the car is too great.

Front

What does Newton's First Law of Motion 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

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the relationship between force and acceleration according to Newton's Second Law?

Back

Force equals mass times acceleration (F=ma).

Front

What is an example of inertia in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops.

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.
