A ramp is an inclined plane. Why would a person want to use a ramp to move a heavy box into the moving truck?
The amount of effort from the person would be less and the force would change.
The amount of effort from the person would be more and the force would change.
It wouldn’t change the force or effort needed; it would only change the direction.
It wouldn’t change the effort from the person.

The man walks outside.
David placed a toy car on a flat plastic track. He pushed the car and measured the distance the car rolled. He followed the same procedure three times. His results are recorded in the data table. What is a valid inference for the 4th trial?
The car will roll 13 cm because the distance the car rolls increases when the strength of the push decreases.
The car will roll 18 cm because the distance the car rolls decreases when the strength of the push decreases.
The car will roll 10 cm because the distance the car rolls increases when the strength of the push increases.
The car will roll 14 cm because the distance the car rolls decreases when the strength of the push increases.
When an object is acted on by unbalanced forces, the object could
Speed up
Slow down
Change directon

Complete the statement: The greater the mass of an object-
the less effort it takes to move the object.
the greater effort it takes to move the object
the easier it is to stop the object when it is moving.
the easier it is to move the object when it is at rest.
The pulley shown above is used to change the —
Amount of mass to be lifted
Direction of the applied force
Weight of the object to be lifted
