Choose the correct statement:
Statement 1: Unbalanced forces can change the direction of motion.
Statement 2: A balanced force is required to accelerate the motion.
Statement 3: An object moves with a uniform velocity when balanced forces are acting on it and there is no net force acting on it.
Statement 4: Balanced force cannot start a motion.
Except statement 2, all other statements are correct.
The cause of motion is a net force. Zero net force causes no motion.
