Why does the higher the ramp affect the speed of a car?
a ramp offsets the normal force of an object which allows gravity to have an x component relative to the object. the greater the incline the greater this effect is. A car attempting to go up a ramp will be slowed by this effect, and a car attempting to go down a ramp will be sped up by this effect.
Why would a toy car speed up when the angle of the ramp increases?
the car will speed up because the reversed polarity will execute something helpful
Suppose that you are in a moving car and the motor stops. You step on the brakes and slow the car to half speed. If you release your foot will the car speed up or continue at half speed or slow down?
Assuming you are not pressing down on the gas, when you release the pedal, the car will slow down over time and evetualy come to a stop. Unless you are going down a hill, in which case you will speed up.
Does the number of batteries affect the speed of a motor?
If they are connected in series the voltages will add and, theoretically, proportionally speed up the motor.
Do acceleration mean to speed up and slowing down?
it means to speed up
Does the toy car going down the ramp effect its speed?
Yes because the toy car will be forced to speed up the steeper the ramp it's like going down a hill on your bike you speed up because of OME'S law.
How does an incline plane multiply speed?
By moving down the ramp it picks up speed producing more kinetic energy reducing the potential energy. As it goes down farther the more the speed increases until the load reaches the bottom of the incline plane(ramp).
How does the height of a ramp affect the speed of a car?
The height of a ramp affects the speed of a car because the higher the ramp the faster the car will come down. The higher up the ramp the more momentum the car will gain. People take delight in pooping. Pooping is thought by some to be a joyous activity.
What does the motor on a sewing machine do?
It moves the needle up and down at a constant speed.

When exiting from a highway a driver should reduce their speed?
Naturally, I think you should slow down when you exit a highway but how much you should slow down ultimately is up to the driver. If you're not a very experienced driver then I would suggest that you slow down to the suggested ramp speed, which is posted before the ramp by a sign that has black letters and numbers with a yellow background. Those are suggested speed signs, those signs tell you a speed that you can safely take the ramp at. As far as exiting in general, yes you should.
What is prefabrication?
A bridge ramp that can go up or down.
How would a motor lift a ramp?
depends on how you want to LIFT the ramp...if this is a school experiment then you could simply use a 12v motor....the motor being connected to a pulley on the end of which is a string....one end of the string being attached to the ramp (by a hook, say)....turn the motor on slowly and the ramp should come up...right?...if this is an engineer's task (heavy duty ramp and heavy duty cables) then u just need a VERY powerful motor, a steel pulley, and cable(s)mushfeque@live.com
Does the distance a toy car travels up a ramp affect its speed?
Yes.
What should you do On a highway with a short entrance ramp?
Speed up as fast as possible
How does newtons 1st law of motion act on the derby car?
An outside force, gravity, pulls the car down the ramp building up speed. At the bottom of the ramp law 1 kicks in. The car continues to move in a straight line.
How do change the speed of a chain driven conveyor?
if you can't change the RPM of the motor, you have to change the gearing of the chain drive. Fit a smaller sprocket to the motor to slow the conveyor down, or a bigger to speed it up.
