Ch.4 Newton's Laws

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 Newton's 2nd law state?

Back

Force = Mass × Acceleration (F = ma)

Front

What is Newton's 3rd law of motion?

Back

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

Front

Define inertia.

Back

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

Front

What is the formula to calculate weight?

Back

Weight = Mass × Gravitational Acceleration (W = mg)

Front

What is a free-body diagram?

Back

A graphical representation showing all the forces acting on an object.

Front

What does it mean for forces to be balanced?

Back

Balanced forces result in no change in motion; the object remains at rest or moves at a constant velocity.

Front

What is the net force?

Back

The overall force acting on an object after all the individual forces are combined.

Front

How do you calculate mass using force and acceleration?

Back

Mass = Force / Acceleration (m = F/a)
