Newton's laws of motion

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 is directly proportional to the net force acting on it and inversely proportional to its mass (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 an unbalanced force?

Back

A force that causes a change in the motion of an object.

Front

What is a balanced force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

How does mass affect acceleration?

Back

If the mass of an object is halved and the force remains the same, the acceleration doubles.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is an example of Newton's 1st Law?

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

What is an example of Newton's 2nd Law?

Back

A heavier object requires more force to accelerate than a lighter object.

Front

What is an example of Newton's 3rd Law?

Back

When you push against a wall, the wall pushes back with equal force.
