Newton's Laws of Motion 2022

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 Law of Inertia?

Back

It is another name for Newton's First Law of Motion, which states that objects tend to resist changes in their state of motion.

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 are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, causing a change in the motion of an object.

Front

What is an example of inertia in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is acceleration?

Back

The rate of change of velocity of an object, which can be caused by an unbalanced force.

Front

What is the relationship between mass and acceleration?

Back

As mass increases, for a given force, acceleration decreases (and vice versa).

Front

What is gravitational force?

Back

The force of attraction between two masses, such as the Earth and an object.
