Since the values are such that a≠αR, hence
rolling motion is not possible on such a surface
.
Can a body roll on smooth horizontal surface?
Statement-1 :
A body cannot roll on smooth horizontal surface
. Statement-2 : When a body rolls purely, the point of contact should be at rest with respect to surface.
What happens when you roll a ball on a smooth surface?
If the motion is pure rolling of a perfectly smooth ball on a perfectly flat surface, then
the friction between the surface and the ball does not do any work in slowing the ball
. … BUT no surfaces are perfectly flat, and any roughness leads to some amount of sliding and therefore some frictional dissipation of energy.
Can a sphere roll on a smooth horizontal plane?
A sphere cannot roll on
a smooth inclined surface and on a smooth horizontal surface because there is no backward force (force of friction) to prevent its slipping.
Can a sphere roll on a smooth inclined surface?
Complete answer:
Due to friction a sphere rolling down a surface will not slip and continue its motion. … For a smooth inclined surface the force due to friction is zero so
a sphere cannot roll on a smooth inclined plane
because for a smooth inclined plane the force of friction is zero.
Is Fair Cannot roll without applying external force on?
A sphere cannot roll on
any smooth surface
as friction is important for rolling to occur.
When a body rolls down a rough inclined plane the work done by friction is zero?
Work done by
pure rolling is always zero
. It is because there is no displacement by force (in case of rolling it is friction). Only in case of rolling with sliding, friction does work.
In which combination the body Cannot roll without slipping on the ground?
A
sphere
cannot roll on a smooth inclined surface.
Can a ball roll forever?
Whenever two bodies undergo relative motion, there comes an existance of kinetic friction. And as friction resists the motion. So due to this friction, velocity of the ball will become zero and the ball will come in its intial rest position. Due to
“Kinetic Friction” ball does not roll forever.
What stops a ball from rolling?
When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because
of friction
.
When you roll a ball across the floor it comes to a stop?
The reason a moving object slows down is that its force of motion gradually runs out. the ground exerts against his foot. When you roll a ball across the floor, it comes to a stop
because you are no longer exerting a force on it
.
Which is true for pure rolling?
In pure rolling, there is no relative motion of the point of contact with the surface when the rolling object speeds up or slows down.
It must accelerate or decelerate respectively
.
Is friction zero pure rolling?
Frictional force is not zero in
a rolling motion An object is able to roll only because friction prevents the bottom part from slipping.
Does a ball rolling on an incline have the same acceleration on the way up as it does on the way down?
A ball rolling on an inclined plane
will not have the same acceleration
on the way up as it does on the way down. Explanation: A ball rolling down on an inclined plane will have a different acceleration than a ball rolling up the inclined plane.
Is sliding faster than rolling?
Since the sliding object has no angular velocity, its
linear velocity is greater than that
of the rolling object, and it reaches the bottom of the track faster.
Is energy conserved in rolling without slipping?
Energy is conserved in rolling motion without slipping. Energy is
not
conserved in rolling motion with slipping due to the heat generated by kinetic friction.
