expression for it.
(3 marks)​

Answer 1

Answer:

The most common definition of weight found in introductory physics textbooks defines weight as the force exerted on a body by gravity. ... "The weight W of a body is equal to the magnitude Fg of the gravitational force on the body." The gravitational acceleration varies from place to place.Since weight acts in the downward direction it will be negative. The total sum of the forces must be zero, in order for the object to be at rest.

Answer 2

Answer:

The most common definition of weight found in introductory physics textbooks defines weight as the force exerted on a body by gravity. This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration.
