Would a rock rolling down a hill be magnetic force?
No. A rock rolls down a hill due to the force of gravity, also known as gravitic force.
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). Read More

Generally, only two forces act on a rolling ball. Gravity and friction (there has to be friction because without it, the ball would just slide). These are pointed directly in the x and y directions. If the ball is rolling down a slope, you can use trigonometry to find the force components. Read More

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). Read More
friction is what slows everything down. if there was no gravity and you rolled a ball across the ground, then the ball would just keep rolling forever Read More
The friction on a rolling object is 2N. So if you have a pencil rolling along a table at a force of 12m/s^2 the force of the pencil would then become 10m/s^2 because you have to allow for fricton. So basically it slows things down. Read More
Yes. If u roll a ball across the floor it accelerates ( net force) but friction opposes it and slows it down until net force is zero when it stops. Read More
Why does a soccer ball that is quickly rolling across a grass field slows down and finally stops rolling?
It will slow down because of the force of friction on the grass field resisting its motion, as well as the force applied by the blades of grass which act like small springs. Read More
On a level surface it is rolling friction. If you arte going uphill it is gravity plus rolling friction Read More
It depends on what direction is considered positive and what direction is considered negative. For this case, I'll assume that up, right, and outward are positive and down, left, and inward are negative. Since the force is perpendicular to the magnetic field, the sign for the force depends on the direction of the current. If the current is inward and the magnetic field is to the left, then the force is upward and thus positive… Read More

The acceleration of a tennis ball rolling down an incline depends with two factors. The force that is applied to the tennis ball and the mass of the tennis ball will determine its acceleration. Read More
Suppose that youre facing a straight current carrying conductor and the current is flowing toward you the lines of magnetic force at any point in the magnetic field will act in?
The lines of magnetic force at any point in the magnetic field of a current flowing towards you will act in the counter clockwise direction. This can be determined by using the right hand rule. Point your thumb in the direction of the current flowing down the straight wire. The curl of your fingers shows the direction of the magnetic lines of flux. The magnetic field of a current is always perpendicular to it. A… Read More
They're alike by both pulling down on something. The only difference is the a certain material is needed for a magnet to use it's magnetic force. Gravity doesn't need anything. Read More
It involves the forces of Gravity. It also involves Friction and Inertia. Read More
A wheel is an example of rolling friction. An example of rolling friction would be if you took kyle leary and folled him down a hill. his fat touching the grond would create rolling friction Read More
Magnetic field lines are not a real observable thing, they are a tool used in physics to picture magnetic fields. A magnetic field is a continuous entity; it has no discrete force lines. Read More
A coin eventually falls over after rolling because of friction and gravity. In a relatively weightless environment, it would keep rolling. Read More
A basketball rolling across a flat floor has translational and rotational kinetic energy. There's a force of gravity pulling the ball down towards the floor, and a reaction force pushing the ball up away from the floor. Read More
Describe a common situation in which the net force on an object is zero but the object is not at rest?
Bowling ball rolling down the lane. Read More
That angle changes with location on the Earth. The only places where the forces of both of them are parallel would be if you were standing at the Earth's north or south magnetic poles. The force of gravity is always nominally toward the center of the Earth (local "down"), with no horizontal component. But the force on a magnet due to the Earth's magnetic field has a horizontal component everywhere, except at the magnetic poles. Read More
magnetosphere, its the magnetic lines of force generated by the moving magma inside the earth. It stops energized particles hitting the earth because a charged particle moving in a magnetic field creates a force perpendicular to the lines of force and the particle spirals down them to strike the earth at the poles. (the magnetic pole just happen to be near the rotational poles at this time) This all is the source of the northern… Read More
If it did, then any rolling object would speed up because of friction. Since everything that rolls actually slows down, the virtual 'force' of friction must be exactly opposite the direction of an object's motion. Read More
Gravity is the force pulling objects down to the ground and magnetism is a force that pulls things with the opposite pull towards itself. Read More

Friction is one force causes a ball to roll downhill. The smaller the static friction coefficient, the more liable the ball will be to skidding instead of rolling. Static friction is involved in a ball rolling downhill. Read More
Wind resistance against the direction which the roller coaster is travelling, friction between the wheels and the surface upon which it is rolling and friction between the brakes and the wheels (if applicable) would all contribute to slow the roller coaster down. Read More

If a wire had a current which was continually reversing directions and hten was placed between the poles of a magnet what would happen to the force on the wire?
Draw an imaginary line between the poles of a horseshoe magnet, say horizontal. If the wire is along that line there will be no magnetic force on it because the current would be parallel /antiparallel to the magnetic field. If the wire is perpendicular to the line, say vertical, the magnetic force on the wire will be in then out. If the wire is perpendicular ,say in/out, then the magnetic force will be vertical up… Read More

Yes but why would i explain and just give that knowledge of power away. sorry Read More
Gravity is pulling the ball down onto the ground. Additionally, if the ball is on a slope of any kind, gravity will be acting to accelerate the ball down the slope. Air friction (drag) is acting on it, as is the "rolling resistance" associated with friction due to its contact with the ground. And it keeps rolling due to inertia it carries in its current motion.

asked this question on yahoo answers and this came up Answer 1 Magnetism generates a force and by itself it is not an energy. You generate energy by letting the magnetic force pull things together. In the same way that a hill is not an energy but if you roll down it you generate energy. To get back to the top you have to put the energy back in. Answer 2 Gauss is the unit… Read More
Since I have read that the path of a projectile is always a parabola, I must say no. The parabolic shape of a projectile's path results from the combination of the force and direction with which it is launched and its weight. A ball rolling down a slope, is not Projectile Motion. While a cannon ball can be used to be a projectile, as far as Physics goes, that is not how it is operating… Read More

The movement through a magnetic field will induce a voltage; if there is a closed circuit, that will produce a current. The current, in turn, will have a magnetic field, which will interact with the external magnetic field. The direction of the interaction will be such that energy is conserved, i.e., it will tend to slow the wire down. Read More
It is because the Sun,our Earth and the center of the milky way are aligned. And a magnetic force slows down the earth's rotation causing all things in the earth will be destroyed but it is true that the sun,earth and the center of the milky way would be aligned but the destruction is not true...
