Newton's Laws

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 an unbalanced force.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

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

Back

Newton (N)

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 the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases if the force is constant.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object.

Front

How do you calculate acceleration?

Back

Acceleration = Force / Mass
