What planet spins the fastest? Jupiter What determines how fast a planet spins? The rotational speed is normally determined by the initial angular momentum when the planet formed, but may also be altered subsequently by large collisions (as for example the collision of the earth with another planet which gave us our moon). Why Jupiter […]

How do you find the force of one object on another? Force exerted by an object equals mass times acceleration of that object: F = m * a . When one body exerts a force on a second body, the second body exerts a force equal in magnitude and opposite in direction on the first […]

Who invented the first electric engine? Michael Faraday What […]

Why we should not ban smoking? Scientists agree that smoking is dangerous. Tobacco smoke can cause cancer, strokes and heart disease. Smoking does not just harm the smoker – it also harms people nearby, who breathe in the smoke (this is called “passive smoking”). Smokers choose to smoke, but people nearby do not choose to […]
