What friction prevents an object from moving when a force is applied?
The friction produced that stops an object moving when force is applied is 'static friction'.
How the direction of the force of kinetic friction is related to the direction of an object's motion?
Friction force works against the motion of the object. In other words friction force has the opponent direction of the velocity of the object.
How can you tell if an object is accelerating?
You know that a car is accelerating because you will be pulled in a direction opposite the force that is accelerating the car. This is Newton's Third Law: "For every force, there is an equal and opposite force".
If friction acting on the car is the action force then what is the reaction force and what object does it act on?
friction is the reaction to motion
What type of friction is the frictional force needed to start on object at rest into motion?
Static
If an object is accelerating then the forces on it must be?
Friction force
What keeps a falling object from accelerating?
Assuming the object is in free fall the only thing that can keep the object from accelerating in the opposing force of kinetic friction upward by air (known as air resistance).
When is static friction applied?
Static friction is not necessarily an applied force, but something that occurs when there is an applied force. Static friction occurs when there is no motion and there is a force being applied to an object on a surface.
Why is it easier to determine the coefficient of kinetic friction if the object moves with a constant velocity?
if moving with constant velocity the only force to slow it down is kinetic friction; if it is accelerating velocity is not constant and an additional force is being applied.
Why does a egg gain speed on the way down?
Any falling object, or object that rolls downwards, can gain speed. This can easily be explained by Newton's Third Law: acceleration = force / mass. Force refers to the net force. So, as long as there is a net force downward, the object will continue accelerating. Only when the upwards forces (basically, friction) become as strong as the downward force of gravity will the object start accelerating. In that case, the object is said to have achieved "terminal velocity".
What do you mean by nullifying friction?
To nullify means to eradicate or end something. Friction is a type of force. To nullify friction you would need to reduce the source that is causing the friction in the first place. Eg. If you have a rolling object there is friction. The faster the object the more intense the friction. Therefore if you stop or slow down the object you nullify the frictional force.
The force that slows something down?
Friction is a force that opposes all movement to slow down a moving object.
What friction prevents an object from moving when a force is applied?
The friction produced that stops an object moving when force is applied is 'static friction'.
What is the friction that hinders a stationary object from moving on a surface when a force is applied to that object?
Static friction. The frictional force is greater then the force applied, meaning the object can't move.
If the force acting upon an object are balanced then the object Amust not be moving Bmust be miving with constant velocity Cmust not be accelerating Dnone of these?
If the force acting upon an object are balanced then the object must not be accelerating
Does it take the same amount of force to start something as it does to keep it moving?
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.
