Which graph could represent a car moving at a constant speed in a forward direction?
Name the force that causes acceleration of an object moving along a circle and keeps the body moving.
centripetal force
centrifugal force
repulsive force
attractive force
For a given force acceleration is inversely proportional to the mass of an object.
A. The above statement is correct because F=ma
B.The statement is not correct because the value of g is constant.
option A is wrong
both option A and B are wrong because the reasons given are wrong
only option A is correct
both A and B are correct.
