Explanation: The fan supplies a force to the cart. If a lower fan speed were used, less force would be applied. This would cause a slower change in the cart's speed. So, the cart would be rolling more slowly than 31.0 cm per second after 5 seconds. The only choice that is less than 31.0 cm per second is 10.9 cm per second.
Explanation: An object will change its speed only if a force acts on it. In the Gizmo, forces can speed the cart up (fan) or slow the cart down (friction). Answer choice A is incorrect because a moving object will keep moving at the same speed if there is no force acting on it (like the cart after the fan was turned off). Answer choice C is incorrect because no force is required for a motionless object to remain at rest. Answer choice D is not correct because a moving object will naturally move in a straight line if there is no force.
Explanation: The cart started at 0 cm per second. Ten seconds later it was moving 20 cm per second. Therefore, every second the cart is gaining 2 cm per second. So, after 11 seconds the speed will be 22 cm per second. After 12 seconds the speed will be 24 cm per second.
Explanation: The cart will continue to speed up because there is still force acting on it. However, less force is acting on it now because the fan speed is lower.
Explanation: The bar graph shows that the speed stayed the same after 8 seconds. This means there is no total force on the cart. This matches the situation in which the fan is off and the surface is frictionless.
