Question

lf a man has a mass 50 kg on the earth, then what is his weight​

Answer 1

Answer:

w=mg

=50*9.8

=490 newto

Answer 2

Mass of the man, m = 50 kg

• Weight is defined as the force acting on the object due to the gravitational attraction acting on the object.

• So weight is almost synonymous to force.

• According to the result of Newton's second law of motion, force is defined as the product of the mass and acceleration.

f = ma

Weight on earth, W = mg

Where g is the acceleration due to gravity on earth.

g = 9.8 m/s²

W = 50 × 9.8

W = 490 N

• Weight of an object is different in different planets, since the weight depends on the acceleration due to gravity of the planet.

• But mass of the object remains same on every planet.
