Friction.
Air friction, road friction and mechanical friction.
a bearing is the angle from north moving clockwise 360 degrees a negative bearing is moving counterclockwise from north
There's no proper reason. It was defined as such. Taking 1 as the denominator we can compare between two things easily like:Two trains are moving with following parametersFirst moving 500 km in 7 hrSecond moving 450 km in 6 hrWe have to determine who is faster... Now at unit (means one) hourFirst train is moving (500/7)=71.42 km per hourSecond train is moving (450/6)=75 km per hourSo clearly we can say that the 2nd train is faster.
The rate of change is often with respect to time t. suppose that d denotes the displacement of a particle, at time t, then you can find the speed with this formula:d=rt, then to solve for r we divide both sides by t and have d/t=rIn mathematics, it is useful to distinguish between velocity and speed. First, when considering motion of a particle in a straight line, specify a positive direction so that it is a directed line. Then the velocity of the particle is positive if it is moving in a positive direction and negative if it is moving in a negative direction. The speed of the particle is the absolute value of its velocity. In more advanced work, when the velocity is a vector v, the speed is the magnitude |v| of the velocity.
Speed X journey time. (Time actually moving).
A moving walkway is something that is used to help people move more quickly between points. They generally move at a speed of 2.5 feet per second, which makes them easy to get on and off of.
The force that keeps a ball moving in a circle is called centripetal force. This force acts towards the center of the circle and prevents the ball from moving in a straight line.
It's not that there is some force keeping the planets from falling into the sun; the sun's gravity prevents the planets from travelling in a straight line out of the solar system. If you throw a ball in a straight line then it keeps going, but if you throw a ball on a rope tied to a pole then the rope pulls the ball toward the pole and keeps the ball moving in a circle.
If there is any horizontal component to the diver's velocity, then that will cause a parabolic path instead of a straight line fall due to gravity.

A centripetal force acts towards the center of the circle, continually changing the object's direction towards the center. This force prevents the object from moving in a straight line and keeps it moving in a circular path.
