The weight of an object is the product of its mass, \(m\), and the acceleration of gravity, \(g\) (where \(g = 9.8 \, \text{m/s}^2\)). If an object’s mass is \(m = 10 \, \text{kg}\), what is its weight?
Express the weight to two significant figures and include the appropriate units.
Answer (3)
Weight = mass x gravitational acceleration = mg
m = 10kg g = 9.8 m/s^2
So, weight = 10 x 9.8 = 98 K g − m / s 2
The weight of the object is 98 N if its mass is 10 kg. ;
The weight of the object is calculated using the formula W = m g , which gives a weight of 98 N. This is rounded and expressed in two significant figures as 98 N. Therefore, the object's weight is 98 newtons.
