Is force always needed to slow down an object?
No, force is not always needed to slow down an object. In cases where there is friction or air resistance, these forces can naturally slow down an object without the need for external force. For example, a ball rolling on a table will slow down due to the friction between the ball and the table surface.
What kind of friction requires more force to overcome rolling friction or sliding?
Sliding friction requires more force to overcome its friction.
Which kind of friction requires more force to overcome rolling friction of sliding friction?
Sliding Friction
What kind of force do you use to move a trolley?
You can move a trolley with a magnetic force (e.g. use magnets to draw the trolley away from it's original position - assuming it is made of a magnetic material), a gravitional force (e.g. rolling the trolley down a ramp) or with an applied force (e.g. pushing the trolley).
What kind of friction require more force to overcome rolling friction or sliding friction?
Sliding friction requires more force to overcome its friction.
What kind of friction requires more force to overcome rolling friction of sliding friction?
Sliding friction requires more force to overcome its friction.
Which kind of friction requires more force to overcome rolling friction friction or sliding friction?
Sliding Friction
What is the kind of rope knot that doesn't move down a rope but moves up freely?
A rolling hitch
What kind of force is in a baseball pitcher's arm?
right arm
Does the speed of a ball rolling down a ramp change with the kind of surfacce on which the ball is rolling?
Yes, the speed of a ball rolling down a ramp can change with the type of surface it is rolling on due to factors such as friction. A smoother surface will likely have less friction, allowing the ball to roll faster, while a rough surface will create more friction, slowing the ball down.
What kind of friction requires more forces to overcome rolling friction or sliding friction?
Sliding friction requires more force to overcome its friction.
What kind of friction requires more forced to overcome rolling friction or sliding friction?
Sliding friction requires more force to overcome its friction.
