Newtons Laws

Front

What type of force(s) will cause a change in an object's motion?

Back

Unbalanced forces cause a change in an object's motion.

Front

Which law is best described by inertia?

Back

The 1st Law of Motion states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What does 'Equal and Opposite' refer to in Newton's Laws?

Back

It refers to the 3rd Law of Motion, which states that for every action, there is an equal and opposite reaction.

Front

What unit do we measure force in?

Back

Force is measured in Newtons (N).

Front

If there is a force of 8 N to the left and 4 N to the right, what is the net force? Is this balanced?

Back

The net force is 4 N to the left, and it is not balanced.

Front

What is Newton's 1st 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 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the relationship between mass and force in Newton's 2nd Law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
