Can gravity and friction speed up and slow down and change the direction of an 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.
What effect does friction have on the speed of an object?
more friction = less speed
Friction will never speed up an object?
Yes, Friction will never speed up an object because friction slows objects down.
Two physical quantities used to describe the motion of an object?
Some of the more basic measurements of an object we can take are time and position (or distance). From these values we can calculate things (like speed and direction) that we use to describe its motion.
Why friction is independent of speed?
Friction is independent of speed because an object could not be moving and still have so friction.
How does friction effects speed?
Friction will reduce an object's speed.
What are the effects of force on object?
Assuming that the force is great enough to overcome static friction; the force will change the momentum of the object.
Does rolling friction push the same direction as the velocity of an object?
If it did, then any rolling object would speed up because of friction. Since everythingthat rolls actually slows down, the virtual 'force' of friction must be exactly oppositethe direction of an object's motion.
What is an object's resistance in speed or direction until an outside force is acted upon it?
friction

What effect does friction have on the speed of an object?
more friction = less speed
How does the force of friction act relative to an object in motion?
It will USUALLY pull the object backwards, in relation to the direction of the motion. This assumes that the material with which it has friction, moves slower than the object you are considering. However, if you put material on a conveyor belt, the force of friction, of the object with the conveyor belt, will pull it FORWARD until the object has the same speed as the conveyor belt.
Friction will never speed up an object?
Yes, Friction will never speed up an object because friction slows objects down.
Does friction speed up an object?
Friction does not speed up an object; it creates drag and slows it down.
What is an object speed and direction?
in terms of speed and direction , in what ways can an object accelerate
Effects of a force on an object?
applying a force to an object, (pushing, pulling, hitting, kicking etc.) can change its speed, its direction and its shape.
How does drag work?
Drag force, or the force of air friction for a falling body, increases with speed. A falling object will reach a speed at which the force of air friction will be equal to and opposite the force of gravity. At that point, the object will no longer accelerate. It's speed will remain constant, and we call that speed (and direction) its terminal velocity.
