Which of the following is a wrong statement (a) change in momentum takes place in the direction of the force (b) In a uniform circular motion, even though the magnitude of velocity remains constant. (c ) Forces acting on a weight balance is an example of balanced force. (d) When you make a sharp turn while driving a car, you tend to lean sideways, due to Inertia of direction.
Answers
Answer:
A statement is incorrect one.
All statements are correct
Explanation:
(a) change in momentum takes place in the direction of the force
True. Newton's second law states that the rate of change of momentum of a object is directly proportional to the force applied on the object, and the change in momentum occurs in the direction of the applied force.
(b) In a uniform circular motion, even though the magnitude of velocity remains constant.
True. In uniform circular motion, direction of velocity is going on changing continuously, but the significance of velocity is constant.
(c) Forces acting on a weight balance is an example of balanced force.
True .The weight of an item and the ordinary pressure appearing on a frame are balanced. The weight acts in the downward direction because of gravity, and the ordinary pressure acts in the opposite direction with same magnitude.
(d) When you make a sharp turn while driving a car, you tend to lean sideways, due to Inertia of direction.
True . When you make a sharp turn while driving a car, you tend to lean sideways. This is explained by Newton's first law of motion.
