gravity and friction
gravity and magnetic force

True
False
I'm not sure
How can we reduce frictional force?

Adding oil to a glass of water.
Which of the following statements about elastic spring force is false?
Elastic spring force is exerted by a spring when the spring is stretched or compressed.
When a force is applied on a spring, the spring extends or becomes longer.
Elastic spring force allows a stretched spring to return to its original strength even if the spring is stretched beyond the limit.
Which of the following statements about gravitational force is true?
Gravitational force only acts on us but not on plants.
It is easier to walk down a slope as we are in the same direction as gravitational force.
Gravitational force pulls all objects outwards to the side of the Earth.
