Why is sliding friction less than static friction?
Because when an object is sliding on the other the molecules donnot get time to inter lock properly
Why wheels help things move faster?
Because rolling friction is usually less than sliding friction. A cart will move easier than a sled.
Why it is easier to roll a barrel on road than to pull it?
When we roll a barrel on the road, rolling friction acts in the direction opposite to the direction of rolling. In case of pulling, kinetic friction acts opposite to the direction in which the barrel moves. The coefficient of rolling friction is almost always less than the coefficient of kinetic friction. So therefore, in layman's terms, rolling friction is less than kinetic friction, therefore less resistance is faced by the barrel while rolling.
What is uphill energy?
Gravitational energy is when an object has more potential energy because of its higher or up hill position. An object rolling down a steep hill will have more energy than one from a lower position.
How does Newton's second law explain why it is easier to push a bicycle than to push a car with the same acceleration?
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.Since a bicycle has much less mass than a car so it's easier to push it.
Why rollhng motion is easier than sliding motion?
Rolling motion is easier than sliding motion because rolling motion has a lower friction force exerted upon the object than sliding motion.
A scientist thinks that is easier to move an object using a wheel and axle than dragging it how could they test it this theory?
Take a rock and try dragging it. Kay, know put it on a cart with wheels. Try again. Which is easier?
Which is easier to stop sliding or rolling friction?
== == AnswersIt is easier to stop sliding friction than rolling friction. The force due to sliding friction will always be greater than the force due to rolling friction. And since friction force will be in the opposite direction of motion it will be easier to stop an object in motion that is sliding than one that is rolling.
What is a rolling friction?
It is the force of friction exerted on an object which is rolling on the floor ;Example:wheels. It is less than the other types of friction.
Is a boat faster than a train?
The average boat is slower than the average train. Dragging a weight through water is a lot harder than rolling the same weight with wheels over rails.
How does a wheel and axle help us?
Because rolling things along takes less force than dragging or carrying them. Good whenever you want to move stuff.
It is harder to stop a rolloing bowling ball than a rolling ping pong ball when both are rolling at the same velocity THis is an example of?
This is an example of momentum, which is a product of the object's mass and its velocity. It is also harder to start a bowling ball rolling than a ping-pong ball due to inertia, which is related only to the object's mass.
Why is sliding friction less than static friction?
Because when an object is sliding on the other the molecules donnot get time to inter lock properly
Why is it easier to change the motion of an object with large mass than an object with a small mass?
Because it is lighter.
What is the principle used in ball bearing?
Bearing principle is very simple: objects rolling easier than slide.
What factor does the rolling budget technique help to overcome?
Rolling budgets have many benefits. They are more flexible than static budgetsÊand allow for changes to be made in the system easier.
Why it is easier to balance a bicycle when in motion than when it is at rest?
It is easier to balance a bicycle when it is rolling forward than when it is at rest because when rolling forward you can easily move the support points, the tire contact patches from side to side by merely steering the front wheel and thus keep them under the center of mass.
