How does the shape of a plane effect the speed?
yes but i dont know how....
When a ball rolls down an inclined plane it gains speed because of gravity?
That's a true statement. Good work!
What effect does a plane mirror have on the speed of light?
A mirror has no effect on the speed of light, but it has a radical effect on thevelocity of the wavefront, because it reverses the direction of the normalcomponent of the velocity.
Would it be correct to say that the Doppler effect is the apparent change in the speed of a wave due to the motion of the source?
No. The Doppler effect is about a change of frequency, not about a change of speed. The relative speed may change as well, but that's not what the Doppler effect is about.
Can i measure a toy cars speed with a inclined plane?
To measure speed, you need a stationary starting poing and finish point, you need a timing device and the object being timed.
Do the surface types on an inclined plane affect the speed of a hot wheel on an inclined plane?
I have no idea why.
What kind of simple machine is a ruler?
A yardstick, a meterstick, a speed suare, a rafter angle square, measuring tape......etc.
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.
Is there a relationship between the mas of a moving ball and its speed while rolling down an inclined plane?
Mass does not affect the acceleration of an object due to gravity. Any object of any size or mass will fall at the same speed. A ball rolling down an inclined plane is accelerated by gravity, so its speed won't be affected by its mass at all.

Does the average speed depend on the steepness of the inclined plane?
Assuming you are asking about an object that is placed on an inclined plane and the only forces acting on it are gravity and friction; as the slope of the plane increases, more of gravitational force is applied down the plane and less of the frictional force is applied to the object up the plane. Unless there is no frictional force, until the plane reaches a certain critical slope the gravitational force will not overcome the frictional force and the object will not move, and the average speed for the object will be zero regardless of the slope of the plane (below this critical slope). As the slope increases there is an increase in the net force on the object down the plane which results in a higher acceleration down the plane, and with a higher acceleration it will reach a higher speed and so the average speed of the object down the plane will be higher. So, yes, it can be said that the average speed of an object down an inclined plane is dependant on the slope of the plane. If there are other forces involved, for example a motor, then the average speed will depend on these forces as well as the slope.

Does the wave speed change in the Doppler effect?
Yes, the Doppler effect defines the change in speed of a sound wave due to motion. As I recall, the Doppler Effect is a change in the frequency of a wave, not its speed. Yep, I'm pretty sure Doppler is a frequency change, not a speed of sound change.
What is needed for light speed plane?
A complete change in the "laws" of physics!
