Newtons Laws Flashcardizz

Front

What is mass?

Back

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

Front

How do you compare the mass of different materials?

Back

Mass is independent of the material; a kilogram of feathers and a kilogram of iron have the same mass.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What does a bathroom scale measure?

Back

A bathroom scale measures the normal force acting on an object, which is equal to the weight of the object when at rest.

Front

What happens to the acceleration of an object rolling down a ramp?

Back

The acceleration of a ball rolling down a ramp is constant, assuming no friction or air resistance.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).

Front

What is the net force acting on an object in free fall?

Back

The net force acting on an object in free fall is equal to its weight.

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 at a constant velocity unless acted upon by a net external 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.
