What's the 2nd law of motion (Formula)?

(a)  

What's the formula for acceleration

(a)  

W = Kg m²/s²

Is work equivalent to the following?

• Yes, it's equivalent

• Yes, it's not equivalent

• No, its not equivalent

• Yesn't

9.8 m/s² is the velocity constant for gravity

• True

• False

Answer explanation

This is because its not velocity. It's acceleration

The gravity acceleration constant is (a)   m/s^2.
