Question 1

Net Force

Answer 1

all the forces acting on an object

Question 2

Newton’s first law

Answer 2

Objects in motion stay in motion until an outside force acts upon it. Objects at rest will stay at rest unless and outside force acts upon it.

Question 3

Force

Answer 3

push or pull of an object

Question 4

friction

Answer 4

a force that acts to resist moving between 2 touching surfaces

Question 5

Static Friction

Answer 5

the type of friction that prevents an object from moving when a force is applied. Static friction gets greater when the surface gets rougher and the object gets heavier. Enough force needs to be applied to overcome static friction

Question 6

Sliding friction

Answer 6

Slows down the sliding object. A force must be applied to move the rough areas of one surface past the rough areas of the other.

Question 7

Rolling friction

Answer 7

friction needed to make a wheel or tire turn. Friction between the tire or wheel and the ground.
