Speed and Velocity Practice Worksheet. 1. Megan rolls a ball down a ramp until the ball hits the wall. The ramp is 2.5 m long and the distance from the end of the ramp to the wall is 1.5 m. If it took 0.5 seconds for the ball to hit the wall then what is the ball’s speed?
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.
(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.

NCERT Solutions for Class 11 Physics Chapter 4 Motion in a Plane Q-1: State whether the following physical quantities are scalar or vector. (i) Mass (ii) Volume (iii) Speed (iv) Acceleration (v) Density (vi) Number of moles (vii) Velocity (viii) Angular frequency (ix) Displacement (x) Angular velocity Solution:
speed. The SI unit of speed is metre per second. This is represented by the symbol m s–1 or m/s. Velocity is the speed of an object moving in aThe other units of speed include centimetre per second (cm s –1) and kilometre per hour (km h–1). To specify the speed of an object, we require only its magnitude. The speed of an object need not ...
