Practice: 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 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 the formula 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 inertia?

Back

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

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 happens when you push against a wall?

Back

The wall pushes back with an equal and opposite force, demonstrating Newton's 3rd Law.

Front

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

Back

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

Front

What is the formula for Newton's 2nd Law?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

How does doubling the force affect acceleration?

Back

According to Newton's 2nd Law, if the force is doubled, the acceleration is also doubled, assuming mass remains constant.

Front

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

Back

When you accelerate a bicycle by pedaling harder, you are increasing the force applied, which increases acceleration.
