Newton's Laws

Front

What happens when the forces are unbalanced?

Back

There is a change in motion.

Front

What is the acceleration of a 2-kg object with a net force of 8 N?

Back

4 m/s²

Front

What does Newton's 1st Law state?

Back

An object at rest or moving at a constant speed in a straight path will continue to do so until a net force acts upon it.

Front

What is an example of velocity?

Back

25 m/s East.

Front

How do you calculate net force?

Back

Net force is the total force acting on an object.

Front

What is Newton's 2nd Law?

Back

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

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = m × a).

Front

What is an example of balanced forces?

Back

Two people pushing a car in opposite directions with equal force.

Front

What is the unit of force?

Back

Newton (N).
