Net force = Mass × Acceleration or F = ma For example, you apply a net force to a ball when you throw it. The harder you throw, the more the ball accelerates. If you double the force, the acceleration of the ...

... Have you ever wondered why and how objects begin to move and why objects stop all of a sudden? An object starts to move, stops moving, or changes directions ONLY when a force acts on it. Some forces act on objects directly and some forces act on objects indirectly. For example, when you push on a do ...

... If the second ramp were extended and its slope reduced, the ball will still reach the same height, but travel further to do so (since the ramp is easier to ascend). If the second ramp were lowered such that it became horizontal, the ball should move forever, forever trying to get back to its origina ...

An object is in equilibrium if the forces acting on it balance meaning that there is no resultant This means that if an object is not in equilibrium it will be accelerating at a rate that is proportional to the size of the resultant force. Conversely, if an object is accelerating it cannot be in equ ...
