A car weighing 1.2 tons is standing on the bridge. Calculate the weight of the car and the force of gravity acting on it.

Given:

m = 1.2 tons is the mass of a car standing on the bridge;

g = 10 Newton / kilogram – acceleration of gravity.

It is required to determine F (Newton) – the force of gravity acting on the car, and P (Newton) – its weight.

Let’s convert the units of mass measurement from tons to kilograms:

m = 1.2 tons = 1.2 * 103 = 1.2 * 1000 = 1200 kg.

Then the force of gravity acting on the car will be equal to:

F = m * g = 1200 * 10 = 12000 Newton = 12 kN.

Since, according to the condition of the problem, the car is at rest, then in this case its weight will be equal to the force of gravity, that is:

P = F = 12 kN.

Answer: The weight and gravity acting on the vehicle will be 12 kN.
