Forces Part A

Front

What type of friction do skydivers experience while falling through the air?

Back

Fluid Friction

Front

What does the term 'force' measure?

Back

Force measures the interaction that causes an object to change its motion.

Front

What type of friction acts on objects when they are rolling over a surface?

Back

Rolling Friction

Front

What is the net force when all forces acting on an object are balanced?

Back

0N

Front

If an object has a net force of 5N, what does this indicate?

Back

The object is accelerating in the direction of the net force.

Front

What is the definition of mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is the difference between weight and mass?

Back

Weight is the force of gravity acting on an object, while mass is the amount of matter in the object.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a)
