Question

Find the mass of an object that has a weight of 910kg

Answer 1

Answer:

91kg

Step-by-step explanation:

weight= mass × gravitational force

910kg = m× 10ms^-2

m= 910÷ 10

m= 91

Answer 2

Answer:

The correct answer is 20 kg.

Given, Weight (w) = 910 N , g = 10 ms-2

So, mass (m) = (w / g) = 91kg

Important Points

Mass is a measure of the amount of matter in an object.

Mass is always constant.Weight is the force of gravity on an object.

Weight depends on the gravitational force of attraction.

Weight (w) = Mass (m) * Gravitational acceleration (g).

The weight of a body is greater in the pole of the earth than in the equator, because of acceleration of gravity at the poles is 980.665 cm/sec2 while at the equator it is 3.39 cm/sec2 less due to the centrifugal force.
