3 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 at the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the definition of inertia?

Back

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

Front

What does F = ma represent?

Back

F = ma is 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 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.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

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

Back

The unit of force is the Newton (N).

Front

What is the formula to calculate acceleration?

Back

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

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

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

Back

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

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move at a constant velocity.
