Friction, Gravity and Force

Front

What is friction?

Back

Friction is a resistance force that opposes the motion of an object.

added.

Front

Forces have strength and direction. True or False?

Back

True

Front

Mass and weight are not related to each other. True or False?

Back

False.

Front

What is gravity?

Back

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

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What happens to the motion of an object when friction is present?

Back

Friction slows down or stops the motion of an object.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Gravity (W = m x g).

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.
