Newton's Laws of Motion

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 happens to objects in a moving vehicle when it suddenly stops?

Back

Objects will continue moving forward due to inertia until an unbalanced force acts on them.

Front

What is inertia?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change its state of motion.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in motion more.

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 the formula for calculating force?

Back

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

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is an example of Newton's Third Law in action?

Back

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