Once a particular reference frame is established, whenever friction is observed between two objects, one of the objects speeds up as a result of the frictional force and one of the objects slows down with respect to that reference frame. Imagine a wooden block at rest on an ideal, frictionless surface. If you were to place something on top of the block and drag it across the surface of the block, the friction that resulted would cause the block to move. Since it started at rest and it ended in motion, it sped up as a result of a frictional force. In this example, since the non-frictional forces (the weight of the something you dragged along the top surface of the block) can only be exerted in the direction of the normal, the only force that is left that could possibly cause any movement of the block is due to friction.
Any frictional force can cause an object to accelerate, but the acceleration is always in the opposite direction of the direction of motion of the object. That is to say frictional forces can cause negative acceleration (or deceleration) of an object in motion.
Lay a bar magnet on a table-top and use another bar magnet to cause an attraction force by putting the north and south ends close together without touching. If the ends are north to north the magnets will repel each other. Both examples will cause the magnets to move without physical contact.
Examples of acceleration are change in speed, change in direction, or both.
Air Resistance, Rubbing, Tire Traction, and Static Friction.
acceleration, deceleration
Acceleration is a measure of the change in velocity over time.
Three factors that affect movement are friction, wind resistance, and velocity. Friction is the resistance that a single object encounters when moving over another object. Velocity is speed, and wind resistance is the opposing force on an object.
Decreasing the mass or Decreasing the velocity
Answer #1:The y intercept should be zero because of Newton's second law. Force andacceleration are directly proportional. The X intercept indicates that there issome force required to overcome friction if friction is not negligible. This valueis the force required to accelerate the object usually very small.===============================Answer #2:It's even easier than that. The graph had better pass through the origin,because zero force on an object means it can't be accelerating, and zeroacceleration of an object means there can't be any net force acting on it.Go back and read Answer #1 above very carefully. It correctly says that they-intercept is zero. But doesn't that mean that the graph must go through theorigin, and that the x-intercept is therefore also zero ? I'm just sayin . . .

Accelerate, motion is generated by applying force to mass.
Yes, an object can accelerate without friction. The only thing that is needed to accelerate an object is net force acting on it should not be zero. Then the accleration of body is given by Newton's 2nd Law: F = m*a . For example Rockets in space experience no friction, but they accelerate due to force on them by the exhaust gases.
Yes it can, by reducing it's speed.
If there is no counter-force (usually friction), the object will accelerate.
Friction is a force that is created when an object or surface moves over another object or surface making the object to resist the direction of motion ( accelerate in the opposite direction).
Cettripetal Force causes an object to accelerate towards the center. The direction changes as the object moves around the center and is not fixed if the object moves.
Take the invention known as a brake. It stops motion. Because friction causes drag, putting friction on one side of a moving object and not on another will cause the object to veer towards the side with friction. That is the principal behind the rudder used in boats.
The object would accelerate faster.
Friction is what causes an object to stop. Friction is cause by having and ridgy type ground forcing the object to stop.
The opposing forces such as friction in case of solids and viscous force in case of fluids are always present in the natural world.a force can cause a resting object to move, or it can accelerate a moving object by changing the object's speed or direction.in a shorter way to say is frictionFriction
Friction causes the object to heat up.
