a. What is the difference between mass and
weight of an object. Will the mass and
weight of an object on the earth be same
as their values on Mars? Why?
b What are (i) free fall, (ii) acceleration
due to gravity (iii) escape velocity (iv)
centripetal force ?
c. Write the three laws given by Kepler.
How did they help Newton to arrive at the
inverse square law of gravity?​

Answer 1

Answer:

I feel like the answer of this question is Acceleratiom due to gravity

Answer 2

Answer:

a...mass is the number of Matter present in an object and weight is the force extend on a body by gravity.no the mass and the weight of an object on the earth will not be same on Mars because earth has more gravity as compared to Mars. therefore on earth,the mass and Weight of an object will be high then their mass and weight on mars
