Speed
VOCAB
1. Motion is a change in position
VOCAB
2. Motion is measured by finding the distance something has moved or an objects displacement
Speed : is the distance an object travels over time
Math Formula : S= d/t
Example: A car drives 100 meters in 5 seconds what is its speed
VOCAB:
Distance: How far an object has moved
Displacement: How far from a starting point(reference point) an object is
VOCAB
D= 100 meters
T= 5 seconds
S= 100/5 = 20 m/s
METRIC UNITS
Distance: Kilometers or meter
METRIC UNITS
Speed(s): Meters(m)/ second(s)
Acceleration
VOCAB
Velocity: Speed in a given direction
VOCAB
Acceleration : Any Change in velocity
Example of Speed: The rocket flew at a speed of 1000 meter/sec
Example of Velocity: The rocket flew at a velocity of 1000 m/s towards the Northeast
Three Types of Acceleration
Speed Up ( positive acceleration)
Slow Down (negative acceleration)
Change direction
Math Formula
Accleration= Final Velocity- Initial Velocity/time
A= Vf-Vi/t
Example: A car drives goes from a speed of 0 m/s to 200 m/s in
10 seconds. What is the cars acceleration
a=Vf –Vi/ t - / 10 = 20 meters per second per second
METRIC UNITS
Velocity(V): Meters/ second
METRIC UNITS
acceleration(a): meters/ second/second
