Betty and Greg are doing an investigation on the power of friction for science class this week. Betty sketches a diagram of Greg pulling a heavy box across the concrete as shown above.
Which of the following best describes how using a box with less mass could help Greg?
The friction will be increased causing the box to move faster across the concrete.
The mass will be decreased causing the box to move faster across the concrete.
The gravity will be increased causing the box to move slower across the concrete.
The mechanical energy will be decreased causing the box to move slower across the concrete.
