Question

identity the wrong statement. A)20kg object has more inertia than an 10kg object B)an object of 30kg has more inertia than an object of 60kg C) objects of 20kg and 40kg have unequal inertia D) Newton used the Atwood machine to prove the laws of motion​

Answer 1

Answer:

c is the write answer

Explanation:

Answer 2

Statement B is the wrong statement.

• Mass of a body is the measure of its inertia.
• From laws of motion we know that F=ma. So a given amount of force will produce more acceleration for a body with less mass than a body with more mass.
• So we can say that more mass implies more inertia i.e. the more the mass, the greater the difficulty of changing its state of motion.
• Hence, an object of 30kg has less inertia than an object of 60kg.
