Question

Which of the following equation is equivalent to the mathematical expression of Newton’s second law of motion? A. F = mv B. Ft = mv-mu C. F= Pv D. F=a/t​

Answer 1

Answer:

✡️ Which of the following equation is equivalent to the mathematical expression of Newton’s second law of motion?

Ft = mv - mu is equivalent to the mathematical expression of Newton’s second law of motion.

• Therefore, option B. is correct.

Explanation:

✴️ As we know that expression of Newton’s second law of motion is ${\red{\sf{F \: = ma}}}$ ; where a denotes acceleration, F denotes force and m denotes mass. Then, by using this expression let us check that Ft = mv - mu is equivalent to it or not!

↦ F = ma

↦ F = m(v-u)/t

↦ Ft = m(v-u)

↦ Ft = mv - mu

• Henceforth, it is verified that Ft = mv - mu is equivalent to F = ma (Newton's second law of motion!)

Additional information:

Newton's second law of motion says that force is the product of mass and acceleration. And the rate in change in momentum is directly proportional to the applied unbalanced force.

About force:

Force: Push and pull on any object is known as force. Force can be also define as the push or pull on an object that have mass that cause the change in velocity of the object.

Effects of force:

1. Force can move a stationary object.

2. Force can stop a moving object.

3. Force can make the change in the size of the object.

4. Force can make the change in the shape of the object.

5. Force can make the change in the speed of the object.

Types of force: There are two types of force that are balanced force and unbalanced force.
