Newton's Laws of Motion

Front

What is Newton's first law of motion?

Back

Newton's first law of motion, also known as the Law of Inertia, states that an object at rest stays at rest, and an object in motion stays in motion, unless acted on by another force.

Front

What does inertia mean?

Back

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

Front

What happens to an object in motion if no forces act on it?

Back

An object in motion will continue to move in a straight line at a constant speed.

Front

What is the relationship between mass and inertia?

Back

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

Front

What is Newton's second law of motion?

Back

Newton's second law of motion states that the acceleration of an object depends on the mass of the object and the amount of force applied.

Front

What is the formula for Newton's second law?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its speed or direction.

Front

What is Newton's third law of motion?

Back

Newton's third law of motion states that for every action, there is an equal and opposite reaction.

Front

Can you give an example of Newton's third law of motion?

Back

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

Front

What is the difference between a scientific law and a scientific theory?

Back

A scientific law describes a consistent relationship observed in nature, while a scientific theory explains why that relationship exists.
