Well aerodynamics are one thing because if you have a car shape like the Nissan Cube it will not go as fast because of it boxy shape but if you have a car shape like like the Lamborghini Gallardo air flow will be easier to go around the car making the go faster but if you do have a car shape like the Gallardo there will be a lot of down force because it is a super car so, yep.
You will need to refer to advances in car technology / road surfacing and general car improvements as well as referring to busier roads and growing population. It is also important to explain why different roads have different limits i.e. why are built up areas generally 30mph refer to statistics on survival if a pedestrian is hit.
the higher or greater the angle the faster the toy car will travel, this is due to gravity.
but
the speed also depends on how you release the car, either u push it or just gently let
yes: because the higher the ramp is the fastest the toy car will travel the lower the ramp is the slower the toy car will go it all depends on the hight that your ramp is. Not the car beacause the toy car has its own ways of going fast and slow.
Increasing the the surface area of reactants in a solid form, the speed of reaction is increased. The contact between the solid reactants or liquids, gases is faster and more complete.
It is all based on velocity. The higher the slope is the faster the car will go, because gravity is pulling on it stronger so the more height the better.
The friction on a ramp increases the speed of a toy car
Smooth and sloped downwards.
No; a denser medium will slow the light down. When the speed of light is quoted, unless otherwise stated, it is implied that it's through a vacuum. The primary example of this is the speed light travels through water or glass. The different speeds are what create the rainbow effect, essentially splitting the light by slowing down different wavelengths at a different rate.
no
Light slows as it enters material with a higher density whereas sound waves speed up in materials of higher density. Light bends towards the "normal" as it passes from a less dense medium to a higher density medium ie air into glass. Both sound and light can be reflected from surfaces.
When temperature rises, the density of the medium changes. Speed of light through a medium is inversely proportional to the density of medium. So when the temperature increases, the density decreases and the speed of light in that medium increases. Note that this is the indirect effect of temperature. If light is travelling through vaccuum , then the temperature will have no effect on the speed of light.
The speed of transmission.
Yes. By Josh L
It depends on the ramp surfaces because some ramp surfaces have less friction than others and some have more friction than others.
Where human mind increases contrast between two surfaces with different luminescence
The answer depends on where the weights are placed.
Yes it does.
Objects move on different surfaces by friction.
yes, of course different surface different amount of friction
Objects move on different surfaces by friction.
Objects move on different surfaces by friction.
It depends on its roughness of the surface. The roughness on the surfaces will tell you how much friction will be acting. It is believed that the friction is caused by the interaction of the particles at sub-atomic level. The greater the interaction between the particles, the greater the friction. The more rough the surface, the less area will interact with both surfaces. Different surfaces, will have different friction coefficients, which decide if the roller skate will slip or not slip.
By reducing the contact surface area of the object and by applying the lubricant between the two contact surfaces lassens or minimizes the effect of friction.
Different surfaces will absorb different amounts of the balls energy
