Unit 3: Forces and Newton's Laws of Motion

Front

What is the fundamental force that deals with the attraction between objects with mass?

Back

Gravitational Force

Front

Is 150 pounds a measure of mass or weight?

Back

Weight

Front

What does Newton's first law of motion state?

Back

An object will remain at rest or keep moving with a constant velocity unless a force acts on it.

Front

What is the formula for force?

Back

F = M * A

Front

Can forces increase or decrease with the speed of an object?

Back

True

Front

What is mass?

Back

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

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = M * g).

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 = M * A).

Front

What is the unit of force in the SI system?

Back

Newton (N)

Front

What is the relationship between mass and weight?

Back

Weight is the gravitational force acting on an object's mass.
