Friction does not speed up an object; it creates drag and slows it down.
Yes, Friction will never speed up an object because friction slows objects down.
False. Friction can speed up an object. For example if you have a wheel, make it spin and then put it on a surface it will speed up. Friction is the force that speeds it up!
You may be thinking of drag instead of friction. Friction between the floor and your foot increases your speed.
more friction = less speed
Friction will cause objects to slow down.
Because friction is when an object resists to another object moving on it, slowing it down. Usually the energy of the moving object is converted to thermal energy.
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.
Friction is independent of speed because an object could not be moving and still have so friction.
Friction is independent of speed once an object is moving since faster does not mean more friction.
It slows the object down.
Since friction reduces motion, if friction is reduced then motion should require less force. If friction is suddenly removed then the object will speed up.
friction is nothing but just the opposite force acting on any moving object...... it hence decreases the speed of a moving object as the object is obstructed in its path
No, friction is the force between to objects created by gravity.
The friction can make you slow down , but if you lose friction you will go at a faster rate of speed
Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
GravityGravity can do all three to an object, the best example of this would be tossing a ball straight up in the air: 1) It initially slows down to a halt at the highest point of ascent, 2) Then speeds up as it falls 3) And of course it changes directions at the top. FrictionFriction, however, is a different matter. Friction that deals with motion (dynamic friction) always acts in the opposite direction of motion; therefore, it cannot accelerate an object in the same direction as it is moving. Due to this, friction can only slow down an object. Can it reverse the direction of motion? Since it cannot speed up an object, it cannot make an object move after friction has slowed it down to a standstill like gravity can from the example above. Thus, in conclusion: gravity can slow down, speed up an object and change its direction; however, friction can only slow down an object.
Yes. For example, if you place an object on a moving conveyor belt, the friction between the object and the conveyor belt will speed it up.
Usually, friction will slow an object down. Here is a counter-example: if you drop something on a conveyor belt (or a similar moving object), friction between the object and the conveyor belt will make the object speed up, until it reaches the speed of the conveyor belt. Two details are worth noting: 1. In the above example, you can also say that the object still slows down, if you take its speed in relation to the conveyor belt. 2. In any case, energy is wasted, in the sense that kinetic energy is converted into heat.
Friction can be affected by the size, weight and material of an object and the speed at which it is moving. It can also be affected by what the object is moving against.
