Momentum Intro

QuestionAnswer
this is conserved in all collisions total momentum
collision where objects hit each other & stick together inelastic collision
collision where objects hit and bounce off each other elastic collision
basic formula for momentum p = mv
Formula for force F = ma
Force = mass x acceleration is which law of motion 2nd law
"Object in motion will remain in motion until acted on by a net force" 1st law of motion
term that can summarize the 1st law of motion ; resistance to change in motion/momentum inertia
if mass is constant, the relationship between momentum and velocity directly proportional
if momentum is constant, the relationship between mass and velocity inversely proportional
states that momentum can only be transferred in a closed system {not created or destroyed] law of conservation of momentum
SI units for momentum kg* m/s
momentum is this type of quantity vector quantity
mass and speed are this type of quantity scalar quantity
amount of momentum objects at rest will have zero
anything that can cause object to accelerate or be displaced Force
this quantity is only conserved in elastic collisions kinetic energy
force times (change in) time impulse
SI unit for force N
car safety features that works by increasing the time of collision to lessen the force of impact air bags & padded steering wheels
car safety features that works by making sure that riders and car share the same momentum seat belts
"for every force there is an equal and opposite force" 3rd law of motion
car safety feature that works by applying grip and traction to the road controlling movement/momentum tire tread
illustration of all the forces acting on an object Free body diagram (FBD)
SI unit for mass kilograms (kg)
ways that kinetic energy can be lost in a collision sound, light, heat, mass deformation
formula for momentum when objects stick together after collision p = (m1 + m2)v

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
