A rolling ball will eventually stop rolling why does it do that?
It will not, unless it is acted upon another force. If it's rolling on something, then friction will stop it (the ball rubbing on the table slows it down).
What are some situations where friction is good and some some where friction is bad?
In situations where you want to create heat or dissipate kinetic energy, friction is usually a good thing. Friction when rubbing your hands together creates heat, which you appreciate, and friction between your brake pad and brake disc slows down your car, which is also a good thing. In situations where you want to maintain kinetic energy or minimize heat, friction is usually bad. Air friction slows down a glider, limiting its range, and mechanical friction in a car rolling on a flat surface causes it to stop without the brakes being applied.
What is the force acting on 2800 kg truck if its slows down from 60 meter per secs. to 35 meter per secs. in 6 seconds?
(-)11,666.67 N. To calculate this, you need to use the impulse-momentum principle, whereby the change in momentum is equal to the force multiplied by the time over which the force is applied. The change in momentum here is the final speed x the mass - the initial speed x the mass. Then divide the answer by the time (six seconds) and the answer will be the force applied (in this case the answer is negative as the force is applied in the direction opposite to the direction of the truck's motion.)
As the ball rises from poin 1 to point 3 it slows down is true or false?
As the ball rises from point 1 to point 3 it slows down - This is True
Slows the motion between two objects in contact with each other?
friction
What force slows a marble rolling flat on a surface?
The force that slows a marble rolling on a flat surface is friction. Because friction is what stops something when it's moving. Like when you throw a ball, it starts going slower, and slower, and slower, until it stops. Why? Well you know a force is involved in something like this! But what kind? It's called: Friction!
What is the force that slows down an object rolling along on a perfectly flat surface?
The force that slows down an object rolling along a flat surface is primarily due to friction between the object and the surface. This frictional force opposes the motion of the object, causing it to decelerate. Additionally, air resistance may also play a role in slowing down the object's motion.
How is rolling friction caused?
Rolling friction is caused by the resistance generated when an object rolls over a surface. It occurs due to deformation of the object and the surface at their point of contact, resulting in a backward force that opposes the motion. This resistance slows down the rolling object.
What do you think causes the marbles to stop rolling?
If you were to roll a marble (across what doesn't matter), what slows the object down is called traction.
A rolling ball will eventually stop rolling why does it do that?
It will not, unless it is acted upon another force. If it's rolling on something, then friction will stop it (the ball rubbing on the table slows it down).
Why rolling friction is less than sliding friction?
Rolling friction is the force of friction between two surfaces when one surface rolls over another.Sliding friction is the force of friction between two surfaces when one surface is moving on another.
What force slows and stops a rolling ball on the moon?
On the moon, the main force that slows and stops a rolling ball is called air resistance. Unlike on Earth, the moon has a very thin atmosphere, so there is less air resistance to slow down the motion of objects. Additionally, the lack of significant friction between the ball and the lunar surface also contributes to its slow down and eventual stop.
Will rolling a marble across a sweater cause friction?
Yes, rolling a marble across a sweater will cause friction. The texture of the sweater will create resistance against the movement of the marble, resulting in friction that slows down the marble's motion.
Does gravity stop a ball from rolling?
No, gravity does not stop a ball from rolling. Gravity actually helps accelerate the ball as it rolls downhill by exerting a force on the ball in the direction of the slope. Friction between the ball and the surface it rolls on is what eventually slows it down and stops it.
When a person stops pedaling the bicycle slows down what force is this?
The force that slows down a bicycle when a person stops pedaling is primarily due to friction. As the pedals stop moving, there is no additional force being applied to overcome the friction between the wheels and the ground, causing the bicycle to slow down.
What is friction what are four types of friction?
Friction is the force that resists motion between two surfaces in contact with each other. The four types of friction are static friction (force between stationary surfaces), kinetic friction (force between moving surfaces), rolling friction (force between a rolling object and a surface), and fluid friction (force between an object moving through a fluid).
What make a moving ball come to rest in a while even if no force is applied?
A moving ball eventually comes to rest due to friction between its surface and the surface it's rolling on. As the ball moves, friction gradually slows it down until it comes to a stop. Without any external force acting on the ball, it will continue to slow down and eventually stop due to this frictional force.
