Document Summary
An object with a constant acceleration of 5m/s^2. An object is released from rest and falls in the absence of air resistance; *the acceleration is constant, velocity would be increasing. All falling objects accelerate at the same rate (ignoring air resistance) *on earth it depends on mass, the amount of matter. Mass itself is a form of potential energy. *a small amount of mass can release a great deal of energy. *concentrated energy can spontaneously turn into particles (for ex in particle accelerators) *it can change form or be exchanged between objects. Gravity itself is a form of energy but is also a force, Closer u come to the sun the faster the planet moves. An asteroid orbits the sun at an average distance of 4au. How long does it take to orbit the. 4au=a p^2=a^3 period of time: amount of time it takes to circle around the orbit.
