Newton's Laws

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 a net external force.

Front

What does F=ma represent?

Back

Newton's 2nd Law of Motion, which states that the force acting on an object is equal to the mass of that object multiplied by its acceleration.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the definition of mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

How do you calculate acceleration?

Back

Acceleration is calculated by the formula a = (final velocity - initial velocity) / time.

Front

What is inertia?

Back

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

Front

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

Back

The relationship is described by Newton's 2nd Law: F = ma.

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 does it mean for forces to come in pairs?

Back

It means that when one object exerts a force on another, the second object exerts an equal and opposite force on the first object.
