How did I calculate my walking and running speed?
I calculated my walking and running speeds similarly. First, I set up 2 cones at a distance of 10m from each other. Next, I walked the distance while being timed and did the same for running. My running and walking times were then put on the Distance, Speed and Time triangle:
- Walking:
Speed
= Distance÷Time
= 10 m ÷ 5.5 sec
= 1.8 m/s
- Distance:
Speed
= Distance÷Time
= 10 m ÷ 2.47 sec
= 4.1 m/s
Why are our weights different on other planets?
This is because your weight depends on the mass of the planet, the distance you are from the center of the planet and the amount of force that is applied on you while you are on the planet. E.g. On earth, you are applied with 10N of force while on the moon you are only applied with 1.6N of force, therefore your weight decreases while on the moon.
