Newton's Laws of Motion

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion. It is not equal and opposite to other forces acting on the object.

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What does Newton's First Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = m x a).

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

How many laws of motion did Newton propose?

Back

Newton proposed three laws of motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m x a, where F is force, m is mass, and a is acceleration.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when a person pushes a stationary car, causing it to move.

Front

What is an example of a balanced force?

Back

An example of a balanced force is when two people push on opposite sides of a box with equal force, and the box does not move.
