Newtons 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 with the same speed and in the same direction 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. This is often expressed as F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Define inertia.

Back

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

Front

What is the formula to calculate force?

Back

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

Front

What happens when the net force acting on an object is zero?

Back

The object is in a state of equilibrium, meaning it is either at rest or moving at a constant velocity.

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s².

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

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

Back

A soccer ball will not move until a player kicks it.

Front

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

Back

If you push a shopping cart, it accelerates faster if it is empty than if it is full.
