Why wheels help things move faster?
Wheels reduce friction by rolling rather than sliding, which requires less energy to move forward. This reduced friction allows objects to move more efficiently and quickly compared to sliding or dragging. Additionally, wheels help maintain stability and balance, further improving speed and maneuverability.
Does it take more force to make a stationary object start sliding or to make sliding object continue sliding?
It takes more force to make a stationary object start sliding because you need to overcome the static friction between the object and the surface. Once an object is already sliding, it requires less force to keep it moving due to kinetic friction, which is typically lower than static friction.
What kind of friction requires more force to overcome rollingfriction or sliding friction?
Coefficient of rolling friction will always be less than that of sliding friction. Hence more force is required to overcome sliding friction. Because the force = coefficient of friction x normal force (ie weight of the body)
How a ramp can make lifting a box easy without changing the amount of amount of work being done?
A ramp can make lifting a box easier by spreading the work over a longer distance. Instead of lifting the box straight up, you can use the ramp to slide it up gradually, which requires less force at any given moment. This allows you to achieve the same amount of work with less effort.
What is rolling friction and sliding friction?
I assume this relates to a wheel. When the wheel is rolling, the surface of the wheel is not moving relative to the surface of the road when they are in contact. however, the wheel deforms slightly and because of this, the normal force slightly opposing the motion of the wheel rather than simply pushing it up. This is rolling friction or more commonly known as static friction. When the wheel is sliding, the wheel is sliding over the road's surface, meaning that there is relative movement between the wheel and the road. this is known as sliding friction or kinetic friction.
Which requires more force lifting the object or pulling the abject along a surface and why?
Pulling it along a surface basically because you don't have to support the weight... In terms of physics lifting the object requires you to counteract the force of gravity while if you push it you just have to overcome friction which is the friction coefficient multiplied by the normal force (which in many cases is the force of gravity)... And since the coefficient is always less than one the force will in all cases be less by sliding it.
What requires less effort sliding a 1 kg box on an ordinary floor or sliding a 2000 kg box on a frictionless floor?
2000 kg box on a frictionless floor

Which type of kinetic fiction is usually greater sliding kinetic friction or rolling kinetic friction?
Sliding Kinetic Friction is usually greater than Rolling Kinetic Friction. Sliding Kinetic Friction is caused by two objects being dragged together, providing more opportunity for the objects' microscopic hills and valleys to catch.

Is sliding friction less than rolling friction?
No.
Difference between rolling and sliding friction?
Rolling friction generates considerably less heat than sliding friction. .
Why kinetic friction is less than sliding friction?
there is more surface area contact with kinetic friction as opposed to sliding friction

Define sliding friction and rolling friction?
Sliding friction is the force that opposes the motion of an object sliding along a surface. Rolling friction, on the other hand, is the force that opposes the motion of an object rolling over a surface. Rolling friction is generally less than sliding friction, making it easier for objects to move when rolling rather than sliding.
