How can perpetual motion be achieved using magnets in a machine?
Perpetual motion using magnets in a machine is not possible due to the laws of thermodynamics. These laws state that energy cannot be created or destroyed, only transferred or converted. While magnets can create motion, they cannot sustain it indefinitely without an external energy source.
Why is perpetual motion with magnets impossible?
Perpetual motion with magnets is impossible because it violates the laws of thermodynamics, specifically the law of conservation of energy. This law states that energy cannot be created or destroyed, only transferred or converted. In a perpetual motion machine with magnets, the system would eventually lose energy due to friction and other factors, leading to a stop in motion.
What type of motion is spinning top uniform or non uniform?
The motion of a spinning top is non-uniform because its angular speed changes over time as it slows down due to friction with the surface. Uniform motion occurs when an object moves at a constant speed in a straight line.
An apple falling down from tree show which uniform or non uniform motion?
The motion of an apple falling from a tree is an example of non-uniform motion. This is because the speed of the apple changes as it falls due to the acceleration of gravity acting on it.
Is a ball rolling down a ramp uniform motion?
No, a ball rolling down a ramp is not considered uniform motion because its speed changes as it moves due to the force of gravity. Uniform motion occurs when an object moves in a straight line with a constant speed.

Is uniform circular motion is accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
Why uniform circular motion is called accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
Why are electron always moves around the nucleus?
Due to Uniform Circular Motion.
Is a ball rolling down a ramp uniform motion?
No, a ball rolling down a ramp is not considered uniform motion because its speed changes as it moves due to the force of gravity. Uniform motion occurs when an object moves in a straight line with a constant speed.
How do perpetual motion machines using magnets work?
Perpetual motion machines using magnets work by harnessing the repelling force between magnets to create continuous motion without the need for an external power source. The magnets are arranged in a way that allows them to repel each other, causing the machine to move in a continuous cycle. However, it is important to note that true perpetual motion machines are not possible due to the laws of thermodynamics.
What type of motion is exhibited by a ball thrown up uniform or non uniform motion why?
If by motion you mean velocity it is non uniform, because the velocity is changing due the acceleration of gravity slowing it down to zero. Then at the maximum height motion is reversed and it accelerates downward back to its original speed but in the opposite direction.
When a bike goes around a curve at the same speed as it was moving on a straight road it has uniform motion this statement is true or false and because?
False. When a bike goes around a curve at the same speed as it was moving on a straight road, it is not considered uniform motion because its velocity is changing due to the direction of the motion changing as it goes around the curve. Uniform motion refers to motion at a constant speed in a straight line.
Why can't a perpetual motion machine be made from magnets repelling each other?
A perpetual motion machine, which produces more energy than it uses, violates the laws of thermodynamics. In this case, magnets repelling each other can create motion, but the system will eventually lose energy due to factors like friction and air resistance, causing it to stop. A perpetual motion machine from magnets alone is not possible because it cannot overcome the law of conservation of energy.
