Question

Choose the correct statement(s):
Statement 1: Unbalanced forces can change the direction of motion of a body.
Statement 2: A balanced force is required to accelerate the body.
Statement 3: An object moves with a uniform velocity when balanced forces are acting on it or if there is no net force acting on it.
Statement 4: Balanced force cannot bring an object at rest to motion.

• A. Only statement 1
• B. Statements 1, 3 and 4
• C. Statements 1, 2 and 3
• D. Only statement 2

Answer 1

The correct option is B

Statements 1, 3 and 4

Balanced forces acting on an object cannot cause any change in the state of motion of the object as in case of balanced forces, the net force acting is zero. If the object is in motion, it will continue in its state of motion, or if the object is at rest, it will remain at rest. In order to change the state of rest or uniform motion of an object, forces acting on it should be unbalanced.
