Study Notes
Throwing an Object into Space
- When a stone is thrown by hand, it falls back to the earth due to gravity
- Using machines, an object can be shot with high speeds, allowing it to reach greater heights
- The greater the initial speed of the object, the higher it scales
Conservation of Energy
- The principle of conservation of energy helps determine if an object can be thrown with a speed that prevents it from falling back to the earth
- According to the principle, the energy of an object is the sum of its potential and kinetic energy
- At infinity, the speed of the object is represented by Vf
Gravitational Potential Energy
- W1 represents the gravitational potential energy of the object at infinity
