Forces & Motion and Newton's Laws

Front

What is a Balanced Force?

Back

A balanced force occurs when two equal forces act in opposite directions on an object, resulting in no change in motion.

Front

What unit is used to measure forces?

Back

Forces are measured in Newtons.

Front

What is an Unbalanced Force?

Back

An unbalanced force is an unequal push or pull on an object that causes a change in its motion.

Front

What does Newton's 1st Law of Motion state?

Back

An object in motion will stay in motion until acted on by an unbalanced force, and an object at rest will stay at rest until acted on by an unbalanced force.

Front

What does Newton's 2nd Law of Motion explain?

Back

The greater the mass of an object, the more force it will take to accelerate the object.

Front

What is Inertia?

Back

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

Front

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

Back

The relationship is that force equals mass times acceleration (F = ma).

Front

What is an example of a Balanced Force?

Back

Two people pushing a car in opposite directions with equal strength.

Front

What happens when an Unbalanced Force acts on an object?

Back

The object will accelerate in the direction of the greater force.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma).
