(a) Magnitude of particle velocity (speed) remains constant. (b) Particle velocity remains directed perpendicular to radius vector. (c) Direction of acceleration keeps changing as particle moves.
Exemplar Problems–Physics 16 3.11 A ball is bouncing elastically with a speed 1 m/s between walls of a railway compartment of size 10 m in a direction perpendicular to walls. The train is moving at a constant velocity of 10 m/s parallel to the direction of motion of the ball. As seen from the ground,
The distance of travel (displacement) can be found by rearranging Eq. $\overline{v}=\frac{\Delta x}{\Delta t}$ for the average velocity. Also note that the units of the velocity and the time are not the same, so the speed units will be converted.
Speed, Distance, Time Worksheet. Use * m/s, km/h, or mph. Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4.
Determine: (a) distance and displacement. (b) average speed and average velocity. Answer: Given: s1 = 6 km to north, s2 = 8 km to east, total time t = 2 h. The runner's route is shown in Fig.3, Fig.3. (a) distance = s1 + s2 = 6 + 8 = 14 km. Displacement = [ (6) 2 + (8) 2] 1/2 = 10 km.
motion along with its speed. The quantity that specifies both these aspects is called velocity. definite direction. The velocity of an object can be uniform or variable. It can be changed by changing the object’s speed, direction of motion or both. When an object is moving along a straight line at a variable speed, we
Speed is the answer to the question, 'How fast?' Velocity is speed with direction. Speed (velocity) is the rate of change of distance (displacement) with time.
