What is the frictional force required to stop a car?
The same amount of force required to push the car.
Which requires more force pulling or pushing?
Pushing.
What force pulls weight down?
Gravity
What factors are true about centripetal force?
Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.
What requires air force agencies to create and preserve records?
Federal Records Act
How much force to lift 50 kilograms onto a shelf 3 meters high?
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

24lbs of weight hanging on a pulley how much force is needed to lift the weight?
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
What kind of friction requires more force to overcome rollingfriction or sliding friction?
Coefficient of rolling friction will always be less than that of sliding friction. Hence more force is required to overcome sliding friction. Because the force = coefficient of friction x normal force (ie weight of the body)
Why force required to move box of same weight changes in case of different surfaces in contact?
Force required to move a box of the same weight changes in the case of different surfaces in contact due to friction.
When raising an object vertically what is the force required?
Any force with a vertical component that equals or exceeds the weight of the object.
What is required for a rocket to lift out of space?
Thrust . i mean a force required to overcome the gravity of earth and which is greater than its weight.
If a block of concrete requires 2500 j to be moved 100m what is the weight of the block?
Work = force x distance;force = work/distance = 2500/100 = 25 Newtons weight which is about 2.5 kg mass
How energy force motion are interrelated?
Force changes motion, according to Newton's Second Law (force = mass x acceleration). Applying a force over a distance requires work (= energy transfer); in the simplest case, this work is equal to force x distance.
What force will give a mass of 1 gram?
Mass is not dependent on the forces applied to it. Weight is the force that a mass exerts due to the acceleration of gravity.
What is meant by centripetal force?
That refers to the force required to keep something moving in a circle. Since the natural tendency of objects is to move in a straight line, it requires a force to make something move any other way.
A fixed single pulley that is used to lift a block does what?
The choices are:A. Doubles the force required to lift the blockB. Decreases the force required to lift the blockC. Makes the block easier to lift by changing the direction of the force needed to lift it.D. Decreases the force required and changes the direction of the force required
Is the force required to keep a rocket ship moving at a constant velocity in deep space equal to the ship's weight?
No. Without friction or air resistance, no force is required to keep an object moving at a constant velocity. Also, by the way, just thought we should mention: In deep space, the ship has no weight.
