Thermal energy transfer by conduction is accomplished when heat moves from a warmer object to a cooler one by –

• moving across a solid barrier
• being carried in a fluid, like air or water
• coming in direct physical contact with it
• traveling through empty space

How could students find out whether a short ramp or a long ramp would require less force to use? Measure the amount of force it takes to move —

• an object up two ramps with the same height, but different lengths
• an object up two ramps with equal heights and equal lengths
• an object up two ramps with the same length, but different heights
• one object up a ramp and a larger object up an identical ramp.

The diagram shows an investigation in a science classroom. Students pulled the same mass up an inclined plane propped up on five blocks, then six, seven, and eight blocks. Each time, they use a spring scale to measure the forces needed to pull the mass up the inclined plane. This investigation can show how which of the following affects the force needed to move an object up an inclined plane?

• The mass of the object
• The height of the inclined plane
• The length of the inclined plane
• The surface area of the objet.

An inclined plane reduces the amount of force needed to move an object by —

• increasing the distance the object moves.
• decreasing the pull of gravity on the object.
• reversing the direction the object is moved.
• transferring more of the force to the object.
