It slows it down, and causes MPG to drop.
able to slow down
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
yes
friction helps the movement of the car by allowing it to move easily and smoothly. -------------- Friction between the tires and the road propels the car forward and steer it. Friction in the brakes helps control the motion.
There are 2 ways that different ramps will alter the movement of a toy car. The material of the ramp will affect the friction (grip) of the car, if the friction is more ON THE WHEELS, it will go faster. If the air friction, or resistance is greater, it will go slower. Also, the height of the 'starting end' of the ramp will make the car go faster becase momentum buils up quicker, so the car will go faster. Hope this was helpfull!
Friction will slow it down
The movement of the car through the air.
it affects it by the contact with the car
Friction is de opposition of motion. if a car is in motion, the friction is said to be reduced because it oppose de movement of the car.
surface friction and sliding friction
Static friction between the wheels and the ground helps provide traction for the mousetrap car to move forward. Rolling friction between the wheels and the axles can also affect the efficiency of the car's movement.
there could be friction inside the motor. there is friction on the wheels of the scooter and the ground. there is air friction when you move on a scooter.
