10. It’s really hard to detect the motion of something very small and very high in a clear, blue sky. This is because _________________________________________________________________
there is no reference point
the object is moving too fast
the sky is too bright
the object is making a sound
11. Distance is defined as_______________________________________________.
the total length of the path between two points
the shortest path between two points
the change in position from initial to final point
the direction from one point to another
Write the formula/equation for velocity.
velocity = distance/ time
velocity = time / displacement
velocity = mass / time
velocity = force / displacement

velocity
direction
density
From start to finish with the direction is the (distance/displacement). Circle the correct term.
distance
displacement
In the measurement, 3.7 m/s East, what is the magnitude?
3.7 m/s
East
3.7
m/s
16. Is 3.7 m/s East a speed, or is it a velocity?
velocity

acceleration
distance
What is the velocity of an object that falls 25 m from a building toward the ground for 7.1 s?
velocity = distnace/ time = 25 m / 7.1 s ≈ 3.52 m/s downward
velocity = distace/ time = 25 m / 7.1 s ≈ 0.28 m/s downward
velocity = distace/ time = 25 m / 7.1 s ≈ 175 m/s downward
velocity = distance / time = 25 m / 7.1 s ≈ 32.1 m/s downward
In the diagram, the bicycler travels from A to C to B and stops at B. The bicycler's distance was ____________________. The bicycler's displacement was ________________________________ ____________________________________________________________ (Be thorough. Don’t forget what all the displacement should include. Assume that A is south of B).
Distance: 7 meters (4 m + 3 m); Displacement: 5 meters north-east (straight line from A to C)
Distance: 5 meters (straight line from A to B); Displacement: 7 meters north-east (sum of all paths)
Distance: 4 meters (A to C only); Displacement: 3 meters north (C to B only)
Distance: 7 meters (4 m + 3 m); Displacement: 7 meters north-east (sum of all paths)
A fox runs 70.84 meters in 9.01 seconds up a hill. Calculate the fox’s velocity. (Include all of the required steps and parts.)
Velocity = Distance / Time = 70.84 m / 9.01 s = 7.86 m/s
Velocity = Distance / Time = 70.84 m / 9.01 s = 8.12 m/s
Velocity = Distance / Time = 70.84 m / 9.01 s = 6.45 m/s
Velocity = Distance / Time = 70.84 m / 9.01 s = 9.20 m/s
fill in the magic triangle to calculate SPEED
S- SPEED
D- DISTANCE
T- TIME
