A friction-like force that opposes the motion of objects that move through the air.air resistanceThe maximum speed an object will reach when falling through a substance, such as air.terminal velocityWhen gravity is the only force acting on an object, that is falling.free fallA force exerted toward the center.centripetal forceIf no external forces act on a group of objects, their total momentum does not change.Law of Conservation of MomentumIf an object is moving at a constant speed, the net force on the object will be_______.zeroIf Ted pushes on a box with a force of 25 N and Richard pushes on the same box, but in the opposite direction with a force of 20 N, what is the net force on the box?5 Newtons in the direction that Ted was pushingIf I shoot a rock from my slingshot straight up into the air, it will eventually slow down and briefly come to a stop before it starts to fall back towards Earth. What causes this type of motion?gravityWhat type of friction is preventing the block from moving down the incline? (see graph, can't put image in)static frictionWhat type of friction would you be experiencing as you ride your sled down a hill moving at a constant speed?sliding frictionBall bearings are parts of a machine that we utilize to eliminate friction, what type of friction do bearing reduce?rolling frictionWhat is the unit used to measure force?Newton (N)What is the unit is used to measure mass?kgWhat is the unit is used to measure acceleration?m/s squaredIf you wanted to experience free fall, we would have to travel to _____________.space ( or somewhere outside our atmosphere)How much force is needed to accelerate a 66 kg skier at 2 m/s2?132 NWhat is the acceleration of a 50 kg object pushed with a force of 500 N?10 m/s2A force of 250 N is applied to an object that accelerates at a rate of 5 m/s2. What is the mass of the object?50 kgA person has a mass of 60 kg, what is this person's weight?588 NCaptain America has jumped off a cliff and is falling towards the ground at a constant speed. If he is experiencing an air resistance of 1000 N, what is Captain America's mass?102 kg
