![]() This is the change of displacement per unit time. Calculate the average speed.Ģ.Ĝalculate the distance in metres covered by a body moving with a uniform speed of 180 km/h in 30 seconds.ģ.Ĝalculate the time in seconds taken a by body moving with a uniform speed of 360km/h to cover a distance of 3,000 km? ![]() It rests for 10 seconds and finally covers a distance of 90m in 60 seconds. The SI unit for speed is metres per second(m/s or ms -1)Īverage speed= total distance covered/total time takenġ.Ě body covers a distance of 10m in 4 seconds. Distance is a scalar quantity since it has magnitude only. This is the distance covered per unit time. The Si unit for displacement is the metre (m). Distance is the movement from one point to another. It is denoted by letter‘s’ and has both magnitude and direction. In kinematics forces causing motion are disregarded while dynamics deals with motion of objects and the forces causing them.ĭistance moved by a body in a specified direction is called displacement.
