Friction can make it easier to accelerate something or harder to. More friction on the object being accelerated means it is more difficult to accelerate it. You and a friend are pushing a heavy crate down a street from a standing start. It's difficult to accelerate it. Now try the same thing on a street that is covered with ice. (The two of you have spikes on your shoes.) Better acceleration.
Yes. Work has to be done to overcome the frictional forces as well as the work needed to increase the speed of the object. A car travelling at a steady, constant speed on a flat surface still needs a foot on the accelerator pedal to keep overcoming the frictional forces.
Friction will never increase the velocity (speed) of an object acting upon it. When an object slides across a solid surface, the interaction between the molecules from the surface and the object creates friction. Friction is a force that will act upon the object in the opposite direction. Because of this, the object will experience deceleration (slow down) and will eventually come to a complete stop.
Type your answer here.friction brings about wear and tear in a moving body .it produces heat.alot of energy wasted by overcoming friction.however if there is no friction a body will slipp or will not move .even though a substanse which is moving will not stop and we cant walk in the earth surface there for force of friction is a nescesary evil
Friction tends to make things go more slowly. It can help in the transfer of power in some cases, for instance, without friction between the tires and the ground, a vehicle cannot move.

Yes it does. The more "rough" the texture is, the more friction there will be. This will cause a decrease in speed and acceleration.
If you are asking the rate of acceleration on a surface, than the larger the force of gravity is, the more it will affect the rate of acceleration. The amount of friction depends one many variables, one of which is gravity. The larger your force of gravity is, the larger the force of friction is. Because of this, the more the force of gravity is, than the slower the rate of acceleration is because of the larger force of friction, which would be acting against the rate of acceleration. Therefore, the force of gravity does affect the rate of acceleration.
The frictional force(f) = μ *mg for horizontal motion, where μ = coefficient of friction, m = mass of the object, g = acceleration due to gravity. Hence friction depends upon the weight of the object.
-- friction in the pivot -- air moving past the pendulum -- the effective length of the pendulum -- the local acceleration of gravity

It reduces the acceleration of the falling object due to friction.
They affect the acceleration of bodies.
Friction provides a force, and therefore an acceleration, in the opposite direction of motion.
If you are asking the rate of acceleration on a surface, than the larger the force of gravity is, the more it will affect the rate of acceleration. The amount of friction depends one many variables, one of which is gravity. The larger your force of gravity is, the larger the force of friction is. Because of this, the more the force of gravity is, than the slower the rate of acceleration is because of the larger force of friction, which would be acting against the rate of acceleration. Therefore, the force of gravity does affect the rate of acceleration.
Friction usually reduces the net force and the resulting acceleration.
Air resistance causes friction and slows an object.
Air resistance creates friction and slows a falling object.
Yes it does. The more "rough" the texture is, the more friction there will be. This will cause a decrease in speed and acceleration.
friction decreases the acceleration of a car by creating a greater force which pushes against the acceleration force. the friction is a force, but more of it means that whatever is pushing against it ( acceleration in this case) is made smaller.
The force on a body determines its acceleration, speed depends on how long the acceleration lasts. Wind resistance and road friction (or other mechanical drag) will affect the power required to maintain a certain speed.
No a cart is a vehicle. Friction is resistance to a change in acceleration.
