Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.

Front

What is Newton's Second Law of Motion?

Back

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

Front

What is Newton's Third Law of Motion?

Back

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

Front

How do you calculate force using mass and acceleration?

Back

Force (F) is calculated by multiplying mass (m) by acceleration (a): F = m × a.

Front

If a 50 kg object is pushed with an acceleration of 3 m/s², what is the force?

Back

150 Newtons.

What happens to a skateboarder when their board stops suddenly?

Back

The skateboarder continues to move forward due to inertia, demonstrating Newton's First Law.

Front

What is inertia?

Back

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

Front

What is the net force when two forces act in opposite directions?

Back

The net force is the difference between the two forces, acting in the direction of the larger force.

Front

If Buster pulls with 20 N to the left and Bingo pulls with 50 N to the right, what is the net force?

Back

30 N in Bingo's direction (right).

Front

According to Newton's First Law, what will happen to an object at rest?

Back

It will stay at rest unless acted upon by an external force.
