Answer on Mechanics | Kinematics | Dynamics Question for ezekiel
if the speedometer of a car indicates a constant speed of 40 km/h, can the car accelerate? Why?
It is possible that the car has
a centripetal acceleration that changes the direction of movement (e.g. the car
is making a curve or constantly racing within a circular loop) while the speed
(magnitude of the velocity) stays the same. The acceleration thus influences
only the direction of the velocity vector.
