The diagram represents a person using a spring scale to pull a wooden block up a ramp. The plastic straws were placed under the wooden block to

• decrease the mass of the block

• decrease the amount of friction

• increase the surface area of the ramp

• increase the gravitational attraction of the block

Newton's first Law of Motion states that if an object is at rest and there is no net force acting on an object it will:

• remain at rest

• move with constant velocity

• have no acceleration

• all of the above

If the car above is moving at a constant speed, what is the Net Force acting on the car?

• 0N

• 10N

• 50N

• 100N
