#1 Newton's Laws Review

Front

What is Newton's 1st law of motion?

Back

An object at rest stays at rest unless acted on by an unbalanced force (inertia).

Front

What does mass measure in terms of motion?

Back

Mass is a measure of an object's inertia; greater mass means greater inertia.

Front

What is the formula for Newton's 2nd law of motion?

Back

F = ma (Force equals mass multiplied by acceleration).

Front

If a net force of 15 N causes an object to accelerate at 5 m/s², what is the mass of the object?

Back

m = 3.0 kg.

Front

What does Newton's 3rd law state?

Back

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

Front

How does inertia relate to mass?

Back

Objects with greater mass have greater inertia, making them harder to accelerate.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is directly proportional to mass and acceleration (F = ma).

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is an example of Newton's 1st law in everyday life?

Back

A book resting on a table stays at rest until someone pushes it.

Front

How can you calculate the net force acting on an object?

Back

Net force can be calculated by subtracting opposing forces from each other.
