Does the speed of a ball rolling down a ramp change with the kind of surfacce on which the ball is rolling?
yes it does. i just did the experiment.
A cart is rolling down a ramp if the angle of the ramp is increased to make the ramp steeper the cart will do what?
The cart will go faster if the angle increases.
Cart is rolling down a special ramp where there is no friction at all What will happen if the amount of mass on the cart is increased?
The cart will move at a constant velocity.

The cart will move at a constant velocity.
A ball rolling down an incline has its minimum speed?
The minimum speed for a ball rolling down an incline occurs near the top. Gravity will speed the ball up as it travels down.
Is a longer tube better for rolling speed?
Yes because it is just like a ball rolling down a hill; it obviously goes faster.
What are the primary uses of rolling utility carts?
The rolling utility cart comes in the unique flavors of quarks: up, down, love, etc. One must try them to experience the awesome subatomic flavors in each bite.
Is it possible to predict the speed of a marble after rolling down a ramp if you know the height of the ramp?
no impossible
What are the answers to the quiz on Gizmo Force and fan carts?
A fan cart with the fan set to High rolled across a floor. The cart's speeds are shown below. If the fan were set to Medium instead, what could the cart's speed be at 5 seconds? A. 10.9 cm per secondB. 31.0 cm per secondC. 40.1 cm per secondD. 48.3 cm per secondCorrect Answer: A - 10.9 cm per second 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.Force is needed A. for a moving object to keep moving at the same speed and directionB. for a moving object to change its speedC. for a motionless object to remain stillD. to prevent a moving object from turningCorrect Answer: B - for a moving object to change its speed 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.Rebecca puts her backpack on a fan cart and turns the fan on. She then measures the speed each second afterward. At 10 seconds the cart has a speed of 20 cm per second. How fast will the cart be moving at 12 seconds? A. 18 cm per secondB. 20 cm per secondC. 22 cm per secnodD. 24 cm per secondCorrect Answer: D - 24 cm per second 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.A fan cart is moving forward on a frictionless surface. If you change the fan speed from High to Low, what will occur? A. The cart will stop moving.B. The cart will slow down.C. The cart will keep moving at the same speed.D. The cart will continue to speed up, but not as quickly as before.Correct Answer: D - The cart will continue to speed up, but not as quickly as before. 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.The speed-versus-time bar graph for a fan cart experiment is shown below. What could have happened? A. The track was frictionless, and the fan was changed from High to Low after 8 seconds.B. The track was frictionless, and the fan was changed from High to Off after 8 seconds.C. The track was wooden, and the fan was changed from High to Off after 8 seconds.D. The track was wooden, and the fan was changed from Off to Low after 8 seconds.Correct Answer: B - The track was frictionless, and the fan was changed from High to Off after 8 seconds. 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.
What did Galileo discover about the amount of speed a ball gained each second when rolling down an inclined plane?
that it's speed increaded. Acceleration was at its upmost.
Describe an experiment you could perform to determinethe average speed of a toy car rolling down an incline?
roll a car down a hill
What is the speed and acceleration of a ball rolling down a hill?
The acceleration of a tennis ball rolling down an incline depends with two factors. The force that is applied to the tennis ball and the mass of the tennis ball will determine its acceleration.
