Question

1) State which of the following situations are possible and give an example of each of these:
a) a body moving with constant acceleration but with zero velocity
b) a body moving horizontally with an acceleration in vertical direction
c) a body moving with a constant velocity in an accelerated motion

Answer 1

a body moving horizontally with an acceleration in vertical direction-projectile motion

Answer 2

a body moving with constant acceleration but with zero velocity - moment when body changes direction of motion in straight line

Answer 3

uniform circular motion?@Fifciol

Answer 4

no, its simply when you move in straight line with some initial velocity in let's say positive x direction with constant acceleration in negative direction of x( v=v_o -at). There is moment in time when velocity is zero (t=v_o/a) but acceleration is still acting on the object

Answer 5

a body moving with a constant velocity in an accelerated motion- not possible (newton's first law)

Answer 6

in SHM there is a moment of time where the velocity of the particle is zero and acceleration is constant..

Answer 7

acceleration changes all the time

Answer 8

when x=A [A=amplitude] then v=o and that time there is a constant acceleration..

Answer 9

constant means that acceleration is not changing all the time
