D mass, shape, speed

7. Which one of the following statements is not correct?

A) Force can change the speed of an object B) Force can change the shape of an object
C)Force can change the direction of motion of an object
D) Force can change the mass of an object​

Answer 1

Answer:

hey!!!

Explanation:

the answer is c.

mass is the amount of matter contained in a body which can't be changed by force!

Answer 2

6. Force can change C. direction of motion, shape and speed

7. D) Force can change the mass of an object​ is not true.

Explanation:

Force is defined as change in momentum with respect to time.

• Force produces acceleration in the system and that causes change of state of the system.
• Mass is a basic property of a body which can never change subjected to any force.
• The velocity or speed of object changes when unbalanced force is applied because of acceleration.
• There can be change in direction of motion because velocity has magnitude and direction and acceleration can be change any of them.
• There can be change in shape of the body as a result of force applied.
