give an example of motion in which acceleration of an object is against the direction of motion.
A ball thrown upwards
Give one example of motion where an object does not change its speed but it changes the direction of motion continuesly?
State which of the following situations are possible and give an example for each of these:
(a) an object with a constant acceleration but with zero velocity.
(b) an object moving in a certain direction with an acceleration in the perpendicular direction.
