Thus, the speed of a body is usually not constant and the distance travelled divided by time gives us the average speed during that time. For example, for a car which travels a distance of 100 km in 4 hours, the average speed is 1004 = 25 km per hour. Although the average speed of...
Speed = 80 mphTime = 3 hoursUse the rearranged speed formula to calculate the distance.Distance $= Speed \times Time$Distance $= 80\; mph \times 3\; hours = 240$ milesTherefore, the train, when traveling at a constant speed of 80 miles for 3 hours, is 240 miles....
While speed is a scalar quantity, velocity is a vector. A simple way to describe the difference between them is that velocity brings information about the direction of the movement. For example, a car is traveling on a straight-line highway that connects south and north of a territory. If...
One formula you’ll use often in algebra and in everyday life is the formula for distance traveled by an object moving at a constant speed. The basic idea is probably already familiar to you. Do you know what distance you traveled if you drove at a steady rate of 6060 miles...
An object's speed is useful for describing how fast an object moves, while velocity involves an object's displacement in relation to some point. Displacement is a means to locate an object in relation to some reference point. It is a change in position from one point to another....

Speed and velocity are distinct concepts; while speed only considers the magnitude of movement, velocity also takes into account the direction. The formula for velocity is given by velocity (v)=displacement (d)time (t)velocity (v)=time (t)displacement (d), where displacement is the distan...
Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Understand the average speed formula with derivatio
Deriving the Formula for Centripetal Acceleration The centripetal acceleration formula can be derived from combining a few key physics concepts. Let‚’ start by looking at the motion of an object moving at constant speed in a circle. While the speed (magnitude of velocity) is constant, the di...
