What is the approximate weight of a 20-kg cannonball on earth
2 answers:
Answer:
196 N
Explanation:
The weight of an object is given by
where m is the mass of the object, and g is the gravitational acceleration on the planet.
In this example, we have an object with mass m=20 kg, and the value of the acceleration due to gravity on Earth is g=9.81 m/s^2, therefore if we use the above equation we find the weight of the cannonball:

The reason scientists use light years instead of kilometres is becasue a light year is the distance traveled by light in one year, and if we actually did the math (ill just give it to you)
to put that into perspective a kilometer is 1000 meters or 
. if they mesured everything in kilometers they would have to use even bigger numbers than they already do.
