Newton's Laws Flashcard Prep

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 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 = ma)

Front

What is Newton's Third Law of Motion?

Back

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

Front

How do you calculate weight?

Back

Weight is calculated using the formula: Weight (W) = mass (m) × gravitational acceleration (g). (W = mg)

Front

What is the gravitational acceleration on Earth?

Back

The gravitational acceleration on Earth is approximately 9.81 m/s².

Front

What is mass?

Back

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

Front

What is the difference between mass and weight?

Back

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

Front

What type of force pulls objects down towards the Earth?

Back

Gravity is the force that pulls objects down towards the Earth.

Front

What is an applied force?

Back

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

Front

What is a normal force?

Back

The normal force is the support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.
