Main Question or Discussion Point
Why do Moons revolve around planets? If because of gravitational pull, why won't they clash with planets. Please help me get answer to this question!?
No. Although the scale of the picture makes it hard to see, in all three cases the cannonball leaves the cannon at the same angle (horizontal) and only the muzzle velocity is different. The slowest-moving ball (A) seems to making a steeper angle, but what's really going on is that because it's moving more slowly it doesn't travel as far left to right in the time that it takes it drop by a given amount as do the other two.Angle depression of canon and force of which it shoots canon balls varies from ball a to b to c. Angle of depression of firing ball C is @horizontal line
Sorry, that's not how this site works (most of the time). We're here to help people understand physical concepts, and not being spoon-fed the answers is how people learn best. Getting there yourself is how you develop intuition.It would be better if you finally say complete answer bro! ;)
This is incorrect. Velocity does not 'impart a force'. There is no force working against gravity to keep something in orbit. The object simply has to go fast enough so that as it falls it continually misses the ground.What force does velocity impart on an object?
That is the force that has to balance with gravity to keep it orbiting.
