Newtons Three Laws of Motion Flashcard

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 inertia?

Back

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

Front

What does Newton's 2nd Law of Motion state?

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 according to Newton's 2nd Law?

Back

Force (F) = Mass (m) × Acceleration (a).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

How does mass affect the force needed to move an object?

Back

The greater the mass of an object, the greater the amount of force needed to move it.

Front

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

Back

A book resting on a table will remain at rest until someone pushes it.

Front

What happens to a rider when a horse suddenly stops?

Back

The rider continues to move forward due to inertia, illustrating Newton's 1st Law.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration; increasing mass requires more force to achieve the same acceleration.

Front

Can you give an example of Newton's 3rd Law?

Back

When you jump off a small boat, you push the boat backward as you move forward.
