Newton's Laws, Forces and FBD

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd 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 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is a Free Body Diagram (FBD)?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What is gravitational force?

Back

The force of attraction between two masses, such as the Earth and an object.

Front

What is tension force?

Back

The force transmitted through a string, rope, or cable when it is pulled tight.

Front

What is normal force?

Back

The support force exerted upon an object that is in contact with another stable object.

Front

What is applied force?

Back

The force that is applied to an object by a person or another object.

Front

What is air resistance?

Back

The forces that oppose the motion of an object through the air.

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases.
