Does friction increase as speed decrease?
Relative to its surface, friction is constant (this is known as the friction constant). The speed is decreasing on an object because friction is acting on it over a period of time, not because friction is getting stronger.
What is the acceleration of a car going a constant speed of 100?
A car going at a constant speed is not accelerating (its rate of acceleration is zero).
If a car moves at constant speed also moving at constant velocity give an example?
A car moving at constant speed in a straight line is also moving at constant velocity.
Why does a toy car rolling at constant speed down a straight incline track slow down when reaching the base of the incline?
i think this happens due to friction between the ground and the toy car :)
A car is driving at constant speed...... explain why the car will eventually reach a new higher constant speed?
because your going downhill

A race car is traveling at constant speed around a circular track what has to happen to the static friction in order to stay on the track when the speed is doubled?
In that case, the centripetal acceleration - and therefore also the static friction - will increase by a factor of 4.

If a car moves at constant speed also moving at constant velocity give an example?
A car moving at constant speed in a straight line is also moving at constant velocity.
What is the acceleration of a car that travels in a straight line at a constant speed of 135 kilometers per hour?
If a car travels in a straight line with a constant speed, then the car has a constant velocity (determined by direction and speed), and the acceleration is 0.

Is there a net force acting on a moving race car?
The net force on the car acts on the line between the center of the car and the center of the circle. Its strength depends on the size of the circle and the speed of the car.
How do you find force when given a constant speed and force of friction?
If the speed is constant, then the group of forces acting on the object is balanced. So the portion of the force acting in the direction of the motion must be equal and opposite to the force of friction.
A car is moving at a constant speed of 30ms the combined mass of the car and the driver is 1000kg if the driving force is 3000N what is the value of the frictional force?
If the car and driver are moving (along a flat horizontal surface) at constant speed, then there is no acceleration, and the net horizontal force is zero.The applied 3,000N must be canceled by an effective total 3,000N of friction.
What is the acceleration of car that travels in a straight line at constant speed?
Straight line at a constant speed = no acceleration
A car is driving at constant speed...... explain why the car will eventually reach a new higher constant speed?
because your going downhill
What affects the speed of a rolling car?
Friction, gravity, wind resistence(form of friction)
