Freefall
... Conditions/assumptions for freefall projectile • Gravity is the force that causes the acceleration (the change in velocity) • Assume no air resistance during freefall, so acceleration due to gravity is a constant 10 m/s2 • Assume object start from rest (initial velocity will be zero) • Velocity can ...

... People have been very curious about the stars in the sky, making observations for a long time. But the data people collected have not been explained until Newton has discovered the law of gravitation. Every particle in the Universe attracts every other particle with a force that is directly proporti ...
