The mechanical advantage of an inclined plane can be calculated by dividing the inclined plane's length by its height. The mechanical advantage of an inclined plane represents how less work is needed to move an object up a ramp compared to directly lifting it from the ground.
Inclined planes are often used when heavy objects need to be moved to a higher vertical position. Instead of lifting the object up, it can be pushed up a ramp. The ramp allows a lower amount of force to be spread out to accomplish the same task. This is because work is equal to force multiplied by distance. The work stays the same, the distance increases, so the force required is less.Learn More
When an object reaches its terminal velocity, it can no longer accelerate, so its acceleration becomes zero, and it falls at a constant speed. As an object falls freely through the air, it has two forces acting upon it: gravity and drag.Full Answer >
Air resistance is caused by friction between a moving object and the air molecules surrounding it. The energy required to push these molecules out of the way diminishes the object's kinetic energy and correspondingly reduces its velocity.Full Answer >
There are three types of acceleration in general: absolute acceleration, negative acceleration and acceleration due to change in direction. Acceleration is defined as the rate of change of velocity.Full Answer >
