What mechanical motion principle do the brakes in a car or on a bicycle use?
Friction
Which force is reduced with the use of lubricant?
Friction
Should one add static friction and kinetic friction together to find the total friction force?
No. You use whichever applies: if an object is at rest, you use static friction. If it is moving, you use kinetic friction.
What to you use to measure the amount of force needed to pull something?
You can use the force gravity to measure the amount of force, because gravity makes an object tied to a string hang.
What are three energy sources that you use every day?
It can affect in the following ways:- Forward force that we apply to make a motion. Frictional force acts automatically even when we make slightest move. Gravitational force that keeps us from flying up in the sky.
Which kind of force do you use to kick a ball?
Gravity, friction, air resistance, centrifugal force, may be more.
What concept would you use to describe the asteroid's motion?
There's gravity, momentum, centripetal force, and friction involved.
Does a bicycle use force?
A bicycle alone only use up space. But a human riding a bicycle will have to use force to get the bicycle to do anything, by pushing on the pedals, pulling on the handlebar ASO.
When you use the hand brakes on a bicycle what force are you using to change the motion of the bicycle?
There are several force transitions going on in the linkage, but in the actual brake you are using friction to turn speed into heat.The most important one is friction, but apart from that there's a lot of mucking about with mechanics in order to translate the motion by the hand at the lever into something capable of slowing down a wheel.There are several forces needed to make a bicycle brake work IRL. But I assume the one you're asking about is FRICTION.
What mechanical motion principle do the brakes in a car or on a bicycle use?
Friction
Is the force that brakes use to stop car?
friction
Which force is reduced with the use of lubricant?
Friction
How does a friction effect with bicycling?
friction makes riding a bike possible. When the tire presses on the ground, friction acts against the rotation of the tire, fixing the lowest point of the wheel on the floor. This force is transmitted to the axel of the wheel and is what propels the bicycle forwards.
I want to calculate how many Newtons it takes to drag a sticky tennis shoe sole over linoleum. What formula do I use?
You use the formula of finding force of friction. The eq'n is: Force of friction = the coefficient of friction multiplied by normal force.
Should one add static friction and kinetic friction together to find the total friction force?
No. You use whichever applies: if an object is at rest, you use static friction. If it is moving, you use kinetic friction.
The amount of friction depends on what?
Friction depends on the surface that the object is going against. If an applied force is used to push a box on a ground, the friction is the surface of the ground, may the ground be rough or smooth, there is a force that goes against the applied force. Air friction is also a type of friction that many physics question does not account for, because it is a virtually small force.
Is the force that brakes use to stop a car?
friction
