-
Distance
- amount of space between to points
- allways positive
- in:
- m, km
-
Time
- how long it takes for a motion to occur
- in: sec, min, hr
-
Avrage speed
- the total distance divided by the total time of the trip
-
- in: m/s . km/h
-
Instantaneous speed
- speed being travalled at one point in time
- in:
- m/s, km/h
-
Velocity
- speed and direction of a motion
- how fast position is changing
-
Displacement
an object change in position
-
Acceleration,
deceleration
- the change in spped during a cerain time
- *speeding up
- *slowing down
-
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
-
Uniform motion
- same speed travled throughout time
- in: m/s, km/h
-
difference between uniform motion and accelreated motion
- uniform motion - constant speed throughtout the whole time
- accelreated motion - speed is gradualy increasing
-
Newtons third law
every action has an equale reaction
-
-
Newtons first law
- -object in motion likes to stay in motion
- -object at rest like to stay at rest
