Does weight effect car speed

Answer 1

In discussing weight, we are assessing the weight of the rider, not the skateboard itself.

.

In a frictionless world, weight has no impact on the speed of a skateboard. In the real world, more weight means more inertia, which means the friction of the wheels have a proportionately less impact on a heavy skateboarder compared to a light skateboarder. Therefore, a heavy skateboarder will coast a further distance on level terrain, or will go faster down a hill, compared to a light skateboarder.

Answer 2

Yes the weight should affect the speed of a hot wheel because it changes the normal force on the car, which affects the frictional force between the car and the surface beneath it. Also, if the hot wheel moves on a slope, the energy it loses depends on its mass.

Answer 3

Yes, weight can affect a car's speed. A heavier car generally requires more power to accelerate and maintain speed compared to a lighter car. Additionally, a heavier car may have poorer handling and braking performance due to the increased mass.

Answer 4

Yes the more weight a car caries the more power it needs to maintain the same speed and its top speed is reduced as the weight increases

Answer 5

No, weight does not effect speed downhill because the acceleration is only due to gravity, which does not depend on mass of the body if friction is not present.

Answer 6

Yes
