Science 8

• Sir Isaac Newton


  One of the pillars in the study of physics, particularly of motion
• Newton's scientific works


  • Three laws of motion: law of inertia, law of acceleration, law of interaction
  • Became the bases of many discoveries
• Motion and acceleration of an object


  Affected by the forces acting on it
• Greater the force applied to an object


  Higher the acceleration
• Force


  Factor in the amount of work done
• Work


  Amount of work that one can do per unit of time is the measure of one's power
• Work


  Possible because of the energy that one possesses to do it
• Motion


  The change in position of an object over time. It can be described by measuring the object's displacement, velocity, and acceleration.
• Acceleration


  The rate of change of an object's velocity. It can be caused by forces acting on the object.
• Direction


  Forces can change an object's direction of motion.
• Speed


  Forces can increase or decrease an object's speed.
• Forces


  Pushing or pulling actions that can cause an object to change its motion. Forces can be contact forces (direct contact between objects) or non-contact forces (actions at a distance).
