What step do the students need to include in their experimental design to best determine the effect of mass on the speed of the toy cart?

• Determine the total distance the toy cart traveled for each trial.

• Investigate how much force was used on the toy cart for each trial.

• Determine the effect of increasing the force pulling the toy cart.

• Investigate the time it takes a different toy cart to travel for each trial.

Which of the following is the best hypothesis for this experimental design?

• If the mass of the toy cart increases then the toy cart will decrease in speed.

• If the mass of the toy cart decreases then the toy cart will decrease in speed. 

• If the net force on the toy cart increases then the toy cart will increase in speed.

• If the net force on the toy cart decreases then the toy cart will increase in speed.

William and his friends were asked to investigate how the mass of a toy car would impact its ability to stop. They rolled the same toy car with different masses down the ramp shown below. The students made sure that each toy car started at the same speed, but when they changed the mass of the toy car, the car's ability to stop would change. 

 

Which of the graphs below best explains why the toy car's ability to stop changed?
