Speed is the distance an object travels in a specific amount of time. Speed = Distance / timeVelocity is speed in a direction. Velocity = Distance / TimeAcceleration is the change in velocity. Acceleration = final velocity  - initial velocity / timeDistance time graphs - time on X axis; distance on Y axis.

FM 3 PadletGRAVITYDo objects with more mass get pulled toward the Earth faster than objects with less mass? Explain.No. Objects with more mass get pulled at the same rate as object of less mass. Gravity works on all objects the same.Gravity depends on _____mass______and distance________.The more ___mass____________, the greater the force of gravity.When you drop 3 objects, tennis ball, packing peanut, & a ping pong ball, what should happen in a vacuum? Explain.Each object will land at the same time as the others, as gravity works on all objects at the same rate, regardless of their size. In the experiments, why did #4 not happen each time?Air resistance could have played a factor as the packing peanut had less mass so air was working against it easier.Gravity gets  ___weaker_______________ with increased distance.The farther you are from Earth the __weaker _____ the gravitational pull.If you drop a feather and a bowling ball, which will land on the ground first? Explain.The bowling ball will land first because the feather will be more resistant to the air. Is there gravity in space? Explain.Yes there is gravity in space. Planets are in orbit around the sun due to the gravitational pull. However, the farther you get from a large object (sun, moon, star, planet) the less the gravitational force.Which would have more of a gravitational pull, the sun or Earth? Why?The sun would have a greater gravitational pull because it is a larger mass, and the larger the mass the more the pull. Why do astronauts float in space? Astronauts float in space due to less gravity. They are in free fall with the space ship.FRICTIONFriction Notes KEYWhen would be a case where you would need to increase friction?Driving a car in the snow you will need to increase friction so your tires can grip the road. When would be a case where you would need to decrease friction?Ice skating, you want to have less friction so it does not stop the smooth motion needed to skateFriction force will remain ___constant_____________ .Air resistance increases with __speed___________ and __surface_____   __area_______.Friction due to air is called __air resistance__________________________________._Gas________________ and _____Liquid__________ are fluids.Force resisting motion through a fluid is a type of friction called _drag_________.A skydiver jumps out of an airplane.  _Gravity____ causes the skydiver to accelerate toward the ground. As the skydiver falls, his body pushes against the _air___. The air pushes back with a force of _air resistance___________. As the skydivers speed increases, his air resistance also _increases________. Eventually the air resistance will balance the gravity and the skydiver will reach _terminal velocity__________________, which is the maximum velocity of a falling object. Once the skydiver opens his parachute, __air resistance________________ increases, thus he reaches a slower terminal velocity and is able to land safely. DENSITY & BUOYANCYThe upward force on objects in a fluid is called buoyant force.Give an example of buoyancy. Ice floating on water, ships floating on waterDensity is: the measure of the amount of matter packed into a unit volume.Water has a __greater___________ density than air, so water has a __greater___________ buoyant force.When objects floats, the object weighs __less___________ than the fluid it is in.When objects sink, the object weighs __more______________ than the fluid it is in.Label which pictures shows greater density and less density and explain how you know.Greater density    less density       Greater density because there is more mass packed in the volume unit than the picture with less densityBernoulli’s principle states that an increase in the speed of the motion of a fluid decreases the pressure within the fluid. Pascal’s principle states that when an outside pressure is applied at any point to a fluid in a container, that pressure is transmitted throughout the fluid with equal strength.

FM 2 PadletNewton’s Laws1st = Objects at rest remain at rest and objects in motion remain in motion at a constant velocity unless acted upon by an outside force.2nd = The acceleration of an object increases with increased force and decreases with increased mass. The direction in which the object accelerates is the same as the direction of the force.3rd = When one object exerts a force on another, the second object exerts a force equal in size and opposite in direction. Force = Mass x Acceleration; measured in NewtonsGravity's acceleration is 9.8 m/s/sAction/ Reaction pairs act on two objectsBalanced and unbalanced forces act on single object. Momentum = mass in motion   Formula is Momentum = Mass x VelocityCollision is defined as: when two objects in close contact exchange momentum and energy. The conservation of momentum states that: the momentum within a system always stays within the system unless an outside forces acts upon it.
