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.
It reduces the acceleration of the falling object due to friction.
Friction usually reduces the net force and the resulting acceleration.
Friction provides a force, and therefore an acceleration, in the opposite direction of motion.
They affect the acceleration of bodies.
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.
force, mass, friction, and gravity
Frictional force reduces aceleration, a= (F-friction)/m
Friction (including fluid resistance), gravity, electrical forces (which include combustion, muscle activity, and friction)
Air resistance causes friction and slows an object.
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.
Well, gravity is the pull of the earth. So, if a car accelerates, more friction is produced.
Yes it does. The more "rough" the texture is, the more friction there will be. This will cause a decrease in speed and acceleration.
Air resistance creates friction and slows a falling object.
Friction on pulley can be measured by compare theorhetical acceleration from force act and measure the actual acceleration to find the force done by friction.
No a cart is a vehicle. Friction is resistance to a change in acceleration.
ice can affect friction
friction does affect work.
In a vacuum it doesn't A: Since acceleration involves the vector sum of all forces acting on a mass, and resistance to motion (air or fluid resistance, friction, etc) is part of that sum, then shapes that increase or decrease resistance do affect the acceleration of an object as they affect the sum of forces acting on it.
Change Near Earth, doubling the mass of an object will not affect how it gravitationally accelerates (ignoring air friction), but might affect how it accelerates across a pond of water (for the pond, the acceleration is probably not proportional to the mass).
Friction opposes motion. As long as you define the direction in which the object is moving to be positive, the acceleration due to friction will be negative. If you think about it, you start out with positive speed and friction decreases the speed, so adding friction subtracted from the speed. Note: Friction is counterintuitive when you start dealing with rolling without slipping. This answer doesn't address this.
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.
No: this is a common misconception Friction= Normal force* Coefficient of friction where Normal force= Mass* Acceleration due to gravity* Cos(angle of surface) and the coefficient of friction is an intrinsic property of the surface Therefore, only the mass of the object and the surface composition affect friction
-- friction in the pivot -- air moving past the pendulum -- the effective length of the pendulum -- the local acceleration of gravity
