Choose the BEST answer that describes how the mass of an object affects its motion.

• The greater the mass of an object, the slower the motion of the object.

• The greater the mass of an object, the faster the motion of the object.

• The greater the mass of an object, the greater the force to move the object.

• The greater the mass of an object, the greater the distance the object will travel.

Students are investigating how mass affects the force needed to move an object. They attached a wooden block to a spring scale and placed a 10 g mass on top of the block and pulled it 50 cm across the table. Which of the following changes to their setup would result in a larger force reading on the spring scale?

• Using a 20 g mass

• Sliding the block 60 cm

• Attaching a larger spring scale

• Using a circular piece of wood

• Gravity caused the car to speed up when rolling down the ramp and slow down when rolling across the floor.

• Friction caused the card to speed up when rolling down the ramp and slow down when rolling across the floor.

• Gravity caused the car to speed up when rolling down the ramp, and friction caused the car to slow down when rolling across the floor.
