Figure out horizontal force necessary to move an object

In summary, to determine the horizontal force needed to move an object with a coefficient of kinetic friction of zero, it must be greater than the maximum static friction. Once the object starts moving, the kinetic friction value will be zero, meaning it will require no force to keep it moving. An initial impulse is only needed to get the object moving.

how do you figure out horizontal force necessary to move an object if the coefficient of kinetic friction is zero?

It must be just big enough to over come the maxium static friction, then it will drop to the kinetic friction value of zero. But if kinetic friction is zero, it would probably be true that static friction is zero as well. But if you are moving, and you have zero kinetic friction, it takes zero force to keep it moving. You just need to give it an impulse to get it moving in the first place.

thx that helped...i actually figured it out on my own...
 

Related to Figure out horizontal force necessary to move an object

1. What is horizontal force?

Horizontal force is a type of force that is applied parallel to the ground or in a horizontal direction. It can cause an object to move or accelerate in a specific direction.

2. How do you calculate the horizontal force necessary to move an object?

To calculate the horizontal force necessary to move an object, you need to know the mass of the object and the acceleration required to move it. You can then use the formula F = ma, where F is the force, m is the mass, and a is the acceleration.

3. What factors affect the amount of horizontal force needed to move an object?

The amount of horizontal force needed to move an object is affected by the mass of the object, the coefficient of friction between the object and its surface, and the acceleration required to move the object.

4. Can the horizontal force needed to move an object change?

Yes, the horizontal force needed to move an object can change depending on the factors mentioned above. For example, if the mass of the object increases, the force needed to move it will also increase.

5. How can I determine the direction of the horizontal force needed to move an object?

The direction of the horizontal force needed to move an object is always parallel to the ground or in a horizontal direction. It will be in the same direction as the motion of the object.
