Newton's Laws of Motion
Transcript of Newton's Laws of Motion
net force of zero
can be described by All three deal with the same concept An object at rest will remain at rest until acted on by an outside force. An object in motion will remain in motion until acted on by an outside force. In other words: Velocity will remain constant when net force equals zero. Newton's Laws of Motion describe how objects behave. They can all be stated in terms of force. To see what I mean, consider the following scenario: This is called "mechanical equilibrium" In this case velocity remains constant, but if the net force is not zero velocity does not remain constant. acceleration, which is described by A change in velocity is called The acceleration of an object is directly proportional to the force applied to the object. The acceleration of an object is inversely proportional to the mass of the object. AND In other words: This shows force acting ON a single object. The more mass an object has, the less it wll accelerate. We can express this concept as an equation inertia
The more force on an object, the more it will accelerate. It ignores the forces caused BY the object This "push back" can be described by it tends to resist acceleration, it "pushes back" But if an object is being pushed with a force If the object has a net force of zero, it can be described by if it is not accelerating? But can there be forces acting on an object YES! If one object exerts a force on another object they will accelerate in opposite directions. When an object exerts a force on another object, there is a reaction force which is equal in magnitude opposite in direction to the original force. The action and reaction forces are parallel. AND For every action there is an equal and opposite reaction. AND In other words: All forces act in equal and opposite pairs momentum mass acceleration action reaction Can you see the bigger picture?
