Lesson 24: Newton`s Second Law (Motion)
... “When an external, unbalanced force acts on an object, the object will accelerate in the same direction as the force. The acceleration varies directly as the force, and inversely as the mass.” “When an external, unbalanced force…” We are still talking about these external forces, but now we’ve added ...

... Example: The Effect of Speed on Centripetal Force The model airplane has a mass of 0.90 kg and moves at constant speed on a circle that is parallel to the ground. The path of the airplane and the guideline lie in the same horizontal plane because the weight of the plane is balanced by the lift gener ...

... Gravity is a force of attraction that acts between two objects. (examples: Earth and the sun, the moon and Earth, you and Earth) We will just look at the gravity Earth exerts on objects. Earth’s gravity acts downward toward the center of the earth. Gravity causes objects to accelerate downward, whil ...

... A body accelerates when acted upon by a net external force The acceleration is proportional to the net (or resultant) force and is in the direction which the net force acts. This law is commonly applied to the vertical component of velocity. SF = ma ...

... Thus, in uniform circular motion there must be a net force to produce the centripetal acceleration. The centripetal force is the name given to the net force required to keep an object moving on a circular path. The direction of the centripetal force always points toward the center of the circle and ...
