Does sand in the wheels of my in-line skates affect how fast they roll?
no
Why it is easier to roll a barrel on road than to pull it?
When we roll a barrel on the road, rolling friction acts in the direction opposite to the direction of rolling. In case of pulling, kinetic friction acts opposite to the direction in which the barrel moves. The coefficient of rolling friction is almost always less than the coefficient of kinetic friction. So therefore, in layman's terms, rolling friction is less than kinetic friction, therefore less resistance is faced by the barrel while rolling.
Why does the toys can stop before it begins to roll back to you?
Friction and air resistance. All of its kinetic energy gets converted to heat.
What is the force created when an object rolls over a surfaces?
Kinetic friction is any friction between objects that are in contact and have relative motion. The specific term for objects that roll across other objects is aptly called rolling friction. Rolling friction exerts its force in the opposite direction of its motion.
Why do ball if you roll it will stop?
because of the friction.
How does a bowling ball being rolled down a bowling alley have kinetic energy?
Kinetic energy is the energy a moving body - in this case, the bowling ball - has. The ball actually has two forms of kinetic energy: rotational and translational. The rotational energy is the energy of it's spin, and the translational energy is the energy of it's motion towards the pins.
When an object roll over a surface the kind of friction that occurs is called friction?
false
When you roll a ball acrossthe floor it comes to a stop because you are no longer exerting a force on it?
No. That statement is false, mainly because it is not true. When you roll a ball across the floor, it comes to a stop because the inevitable friction where the ball contacts the floor robs it of kinetic energy. If the friction could be eliminated, the ball would not come to a stop. No force is required to keep a moving object moving.
What effect does friction have on a rolling ball?
If there was no friction then the ball would just slide instead of roll
Why does your engine roll over too slow?
the answer is friction
When you roll down a hill is that mechanical energy?
No, It is kinetic energy
How do you make a ball roll slowly down a ramp?
apply friction a rough surface cardboard for example, the rougher it is the slower the ball will roll but to much friction and it will stop altogether.
