Forces and Gravity

Front

What is a force?

Back

A force is defined as a push or pull that can cause an object to move, stop, or change direction.

Front

What are the two main types of forces?

Back

The two main types of forces are contact forces (like friction and tension) and non-contact forces (like gravitational and magnetic forces).

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

Front

What does the strength of gravity depend on?

Back

The strength of gravity between two objects depends on their mass and the distance between them.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion.

Front

What is a balanced force?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is a vector quantity?

Back

A vector quantity is a quantity that has both magnitude and direction, such as force or velocity.

Front

What is a scalar quantity?

Back

A scalar quantity is a quantity that has only magnitude and no direction, such as speed or temperature.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.
