Newton's Laws of Motion and Types of Forces

Front

What is Newton's first 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 does Newton's first law of motion predict about stationary objects?

Back

Stationary objects will remain at rest unless acted upon by an unbalanced force.

Front

What does Newton's first law of motion predict about moving objects?

Back

Moving objects will continue in the same state of motion unless acted upon by an unbalanced force.

Front

What is the condition for Newton's first law to be applicable?

Back

The forces must be balanced; the law applies unless acted upon by an unbalanced force.

Front

How does Newton's first law apply to coffee in a car?

Back

Coffee 'keeps on doing what it is doing.' It spills when the car accelerates or stops because it resists changes in motion.

Front

Why are seat belts important according to Newton's first law?

Back

Seat belts provide the unbalanced force needed to change a passenger's state of motion, ensuring safety.

Front

What is an applied force (Fapp)?

Back

A force applied to an object by a person or another object, such as pushing a desk.

Front

What is the gravity force (Fgrav)?

Back

The force with which a massive object like Earth attracts another object towards itself, equal to the object's weight.

Front

What is the normal force (Fnorm)?

Back

The support force exerted upon an object in contact with a stable object, like a book on a table.

Front

What is the friction force (Ffrict)?

Back

The force exerted by a surface as an object moves across it, often opposing the object's motion.
