Newton's Laws

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is inertia?

Back

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

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

What does 'net force' mean?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What happens when an unbalanced force acts on an object?

Back

The object will change its motion, either speeding up, slowing down, or changing direction.

Front

What is an example of inertia in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops.

Front

What is the formula for calculating force?

Back

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

Front

What is an example of Newton's Third Law?

Back

When you jump off a small boat, the boat moves backward as you move forward.
