Forces and Newton's Laws

Front

What is a force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an unbalanced 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 friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate because the net force acting on the object is not zero.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, usually measured in kilograms.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can be an increase or decrease in speed.

Front

How does gravity affect objects?

Back

Gravity is a force that pulls objects toward each other, giving weight to objects and causing them to fall toward the Earth.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).
