Which type of kinetic fiction is usually greater sliding kinetic friction or rolling kinetic friction?
Sliding Kinetic Friction is usually greater than Rolling Kinetic Friction. Sliding Kinetic Friction is caused by two objects being dragged together, providing more opportunity for the objects' microscopic hills and valleys to catch.
What portion of the total kinetic energy of a rolling object is translational energy?
If an object is rolling without slipping, then its kinetic energy can be expressed as the sum of the translational kinetic energy of its center of mass plus the rotational kinetic energy about the center of mass. The angular velocity is of course related to the linear velocity of the center of mass, so the energy can be expressed in terms of either of them as the problem dictates, such as in the rolling of an object down an incline. Note that the moment of inertia used must be the moment of inertia about the center of mass. If it is known about some other axis, then theparallel axis theorem may be used to obtain the needed moment of inertia.
What happens to the kinetic energy of a snowball as it rolls across the lawn and gain mass?
That depends on what happens to its speed. The formula for kinetic energy is:KE = m(v)^2, in which m is mass in kg and vis speed in m/s.If either the mass or the speed increases, the kinetic energy will increase. So if the mass of the rolling snowball increases, but the speed remains constant, its kinetic energy will increase.However, in reality, due to friction between the snowball and the ground, the speed will decrease until the snowball stops. So the kinetic energy under natural conditions would decrease, even though the mass increases.
Why is a rock on the top of a hill kinetic energy?
A rock on top of a hill has potential energy, not kinetic energy. If it starts rolling down the hill then the potential energy transforms to kinetic energy.
When rolling downhill a rollar coasters potential energy is converted?
Yes. At the top of the hill, the potential energy is at a maximum. As the coaster is rolling down the hill, the potential energy (or energy due to the coaster's position or height), is converted into kinetic energy (as the roller coaster is rushing downhill).

What is an example of constant motion?
A ball rolling at a constant speed at the same rate of speed on a still surface.
Is a rolling marble a kinetic or potential energy?
A rolling marble has kinetic energy due to its motion.
What kind of energy does a rolling toy have (rolling toy)?
It has kinetic energy.
What is one example of rolling friction?
rolling paper becuse it produce kinetic friction and kinetic energy
Does a ball rolling have kinetic energy?
Yes, a rolling ball has kinetic energy due to its motion. The amount of kinetic energy it has depends on its mass and velocity.
What is one example of rolling kinetic friction?
Anything with wheels, such as a car, would be an example of use of rolling kinetic friction.
Descrbe a real world situation where there is zero acceleration but some velocity.?
-- a car on cruise control rolling along at a constant speed on a straight section of highway -- a golf ball or squash ball rolling across the gym floor at a constant speed
What are the examples of uniform linear motion?
There are loads of things that are linear like a car on driving on a road in a straight direction going so it's basically a thing that goes in a straight line!! Another one is a conveyor belt taking food from point A to point B. Another one is a train!
What is the state of equilibrium of a rolling ball?
The state of equilibrium of a rolling ball occurs when the forces acting on it are balanced, resulting in no acceleration. In this state, the ball will continue rolling at a constant speed in a straight line unless acted upon by an external force.
Is a wagon rolling down the side walk kinetic energy or potential energy?
kinetic energy
If a ball is rolling in a straight line and you push it to the right velocity Will?
If you push the ball to the right velocity in the same direction, it will continue moving in a straight line with the new velocity. If there are no other forces acting on it, it will maintain constant velocity due to inertia.
Which type of kinetic fiction is usually greater sliding kinetic friction or rolling kinetic friction?
Sliding Kinetic Friction is usually greater than Rolling Kinetic Friction. Sliding Kinetic Friction is caused by two objects being dragged together, providing more opportunity for the objects' microscopic hills and valleys to catch.
