If an object has a mass of 20 kg on a planet with a force of gravity of 4 m/s2. What is the object's weight? **Remember** W=mg a 80 N b 5 N c 200 N d 0.2 N
To find the weight of the object on the planet, we can use the formula:
Weight (W) = mass (m) * gravity (g)
Given that the mass of the object is 20 kg and the force of gravity on the planet is 4 m/s^2, we can substitute these values into the formula:
W = 20 kg * 4 m/s^2
W = 80 N
Therefore, the weight of the object on the planet is 80 N. The correct answer is a) 80 N.
