The conversion of Potential Energy (the energy something has as a result of its position in a gravity field) into Kinetic energy (the energy of a mass in movement).
I have no idea why.
An inclined plane can affect the speed of an object by decreasing it due to friction between the object and the surface of the inclined plane. The steeper the incline, the more the speed will be reduced. Additionally, the length of the inclined plane can influence the object's speed as it may take longer for the object to travel the length, thus affecting its overall speed.
Depends on the speed at which the plane was traveling.
Apart from the fact that a jet plane would stall at that low a speed, the speed is equivalent to 36.657 metres per sec
20mps
Galileo discovered that the speed gained by a ball rolling down an inclined plane is constant and increases linearly with time. This led to the development of the concept of acceleration, where an object's speed changes at a constant rate over time.
That depends on the speed at which one is traveling.
That depends on the speed at which one is traveling.
150 MPH
That depends on the speed at which one is traveling.
Assuming you are asking about an object that is placed on an inclined plane and the only forces acting on it are gravity and friction; as the slope of the plane increases, more of gravitational force is applied down the plane and less of the frictional force is applied to the object up the plane. Unless there is no frictional force, until the plane reaches a certain critical slope the gravitational force will not overcome the frictional force and the object will not move, and the average speed for the object will be zero regardless of the slope of the plane (below this critical slope). As the slope increases there is an increase in the net force on the object down the plane which results in a higher acceleration down the plane, and with a higher acceleration it will reach a higher speed and so the average speed of the object down the plane will be higher. So, yes, it can be said that the average speed of an object down an inclined plane is dependant on the slope of the plane. If there are other forces involved, for example a motor, then the average speed will depend on these forces as well as the slope.
A gear is neither a lever nor an inclined plane. Gears are mechanical components with teeth that mesh with each other to transmit motion and power. They are used to change the speed, torque, and direction of rotation in machines and other systems.
