Front

Which of Newton's laws states that an object at rest stays at rest unless acted upon by a force?

Back

Newton's First Law

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

Front

What type of force is exerted when two objects are in contact?

Back

Contact force

Front

What is an example of torsion?

Back

Turning a door knob.

Front

What does Newton's Second Law explain about acceleration?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

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.
