Allen pushes a toy car across three different surfaces. He pushes the car across a wooden floor, a tile floor, and a carpeted floor. He notices it is hardest to push the toy car across the carpeted floor. Which is the MOST likely reason it is hardest to push the car across the carpet?

• The car has more mass when it is on the carpeted floor.

• The carpet creates more friction than the other surfaces.

• The car is affected most by gravity on the carpeted floor.

• The carpet pushes more against the car than the other surfaces.

Brandon made a parachute for his action figure by taping a thin plastic sheet to pieces of string. Brandon tied the strings to the action figure. When he threw the action figure in the air, it fell back to the ground quickly.

What can Brandon do to make the action figure fall to the ground more slowly?

• use shorter pieces of string

• use a larger sheet of plastic

• add weights to the action figure

• throw the action figure higher into the air

Two students are investigating kinetic energy using a wooden board and a tennis ball. One student holds the end of the board, and the other student places the tennis ball on it. The tennis ball rolls along the board to the ground.

What could be done by the student holding the board in order to increase the kinetic energy of the tennis ball as it rolls down the board?

• tilt the board to the left

• tilt the board to the right

• raise the end of the board

• lower the end of the board

Jan has two identical magnets on her metal cabinet. She hangs a drawing using Magnet 1. She tries to hang a calendar using Magnet 2, but the calendar falls to the floor.

Which BEST explains why Magnet 1 can hold up the drawing but Magnet 2 is unable to hold up the calendar?

• The area near Magnet 1 has extra metal.

• The calendar is longer than the drawing.

• The area under Magnet 2 has more gravity.

• The calendar has a greater mass than the drawing.
