The flashcards below were created by user sim11r on FreezingBlue Flashcards. What would you like to do?

1. Distance
• amount of space between to points
• allways positive
• in:
• m, km
2. Time
• how long it takes for a motion to occur
• in: sec, min, hr
3. Avrage speed
• the total distance divided by the total time of the trip
• in: m/s . km/h
4. Instantaneous speed
• speed being travalled at one point in time
• in:
• m/s, km/h
5. Velocity
• speed and direction of a motion
• how fast position is changing

• in:
• m/s, km/h
6. Displacement
an object change in position

• in: m, km
7. Acceleration,
deceleration
• the change in spped during a cerain time
• *speeding up
• *slowing down

8. differnce between distance and displacement
• distance is the how far someone/ something travled in total: ex: walk to the park 1km walk back home 1km total ditance walked 2km
• displacement is were the person/objecet location compered to starting point:
• ex dining table (0,0) displacemet, walk to fridge at (1,5) displace ment then walk back to table you are ones again at (0,0) displacement

9. Uniform motion
• same speed travled throughout time
• in: m/s, km/h
10. difference between uniform motion and accelreated motion
• uniform motion - constant speed throughtout the whole time
• accelreated motion - speed is gradualy increasing
11. Newtons third law
every action has an equale reaction
12. Newtons second law
13. Newtons first law
• -object in motion likes to stay in motion
• -object at rest like to stay at rest
