Forces and Motion

Front

What is a force?

Back

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

Front

What are the two types of forces?

Back

The two types of forces are contact forces (forces that require physical contact) and non-contact forces (forces that act at a distance, like gravity).

Front

What is gravity?

Back

Gravity is a non-contact force that pulls objects toward each other, most notably the attraction between the Earth and objects on its surface.

Front

What is the difference between a push and a pull?

Back

A push moves an object away from the source of the force, while a pull brings an object closer to the source of the force.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

How does mass affect the force of gravity?

Back

The force of gravity increases with the mass of the objects involved; more massive objects exert a stronger gravitational pull.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law of motion, force equals mass times acceleration (F = ma).

Front

What is the concept of net force?

Back

Net force is the total force acting on an object when all the individual forces are combined.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not cause a change in motion, while unbalanced forces result in a change in motion.

Front

What is position in physics?

Back

Position refers to the location of an object in relation to a reference point.
