Newton's 2nd Law of Motion
Newton's 2nd Law of Motion
Newton's 2nd Law of Motion is that the more force you apply to an object the more it accelerates and the other way around. The equation for this law is F=mxa. This means that force equals mass times acceleration. If you use more force on an object than the acceleration will increase. If the mass increases but force stays the same the acceleration will decrease.
Newton's Three Laws of Motion
Law of Inertia
Law of Inertia
Newton's First Law of Motion
Objects in motion stay in motion, objects at rest stay at rest. The more mass an object has the more inertia.
EX. A ball will stay at rest unless an unbalanced force acts upon it. When someone kicks it, the ball is now in motion.
Law of Force, Mass, and Acceleration
Law of Force, Mass, and Acceleration
Newton's Second Law of Motion
The more force you apply to an object the more it accelerates and the other way around.
EX. If someone uses 20N of force on an object and the object weighs 5kg, it will move at 4m/s2.
Law of Action and Reaction
Law of Action and Reaction
Newton's Third Law of Motion
Forces always act in pairs, forces are equal and opposite, and for every action there is an equal and opposite reaction.
EX. If you push off a skateboard, the skateboard is pushing back on you with an equal force.
Inertia
Inertia
Is the tendency for an object to resist a change in motion. The more mass an object has, the more inertia. Mass and inertia are related because if an object has more mass it has more inertia and the other way around.
