Newtons Laws Review

Front

What is Newton's First 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 is Newton's Second 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. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the formula to calculate force?

Back

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

Front

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

Back

Newton (N)

Front

What does acceleration measure?

Back

Acceleration measures the rate of change of velocity of an object.

Front

What is inertia?

Back

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

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

How do you calculate acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m)

Front

What is the relationship between mass and acceleration?

Back

As mass increases, acceleration decreases for a given net force.
