**Unformatted text preview: **Name: ______________________________________ Speed and Velocity Web Quest
1. What is the measurement of how fast an object moves relative to a reference point?
Velocity is the speed of an object plus its direction. Speed is called a scalar quantity and
velocity is a vector quantity. The fastest possible speed in the universe is the speed of light 2. What is the formula for speed?
'speed = distance/time' 3. How do we measure or think of speed in the United States?
we mostly think of speed in miles per hour or mph. This is the way the
speed of a car is typically measured 4. In science and physics, what is the standard unit of measure for speed?
is generally meters per second or m/s 5. What is the speed of an object at a given moment?
The car may be travelling at 50 mph at this moment, but it may slow down or speed
up during the next hour. Average Speed 6. Give an example of instantaneous speed. a cheetah who is running with speed of 80 miles per hour then it is his instantaneous
speed because it is shown as in per hour speed. 7. What is the average speed of a car that travels 40mph for 1 hour and 60 mph in another
hour? 50 miles per hour 8. What is the rate of change in an object’s position?
acceleration 9. What two parts make up velocity?
direction and speed 10. Who was the first scientist to measure speed as distance over time?
Galileo 11. What is good example of instantaneous speed?
a cheetah who is running with speed of 80 miles per hour then it is his instantaneous
speed because it is shown as in per hour speed. Scroll to the bottom of the page and click on “Acceleration.”
1. What is the measure of a change in an object’s velocity?
v = Δs/Δt 2. What is the equation for acceleration?
v = u + at. 3. What is the standard unit of measure for acceleration?
dividing meters per second [m/s] by second [s]
1. What is where an object is located?
position 2. What is how fast an object’s speed is changing?
speed 3. What is how fast an object is moving?
acceleration 4. Choose each of the settings that follow and list them below:
First object = sporty utility vehicle
Position = 5 m
Speed = 2.5 m/s
Acceleration = 6 meters/second*second Second Object = motorcycle
Position = 1 m
Speed = 10 meters/second
Acceleration = 10 meters/second*second What reached the finish line first? Why?
The motorcycle reached the finish line because its speed and
acceleration is quicker then the sporty vehicle 5. Now try again with different settings:
First object = sporty utility vehicle
Position = 1 m
Speed = 10 meters/second
10 meters/second*second
Acceleration = Second Object = motorcycle
Position = 5 m
Speed = 2.5 m/s
Acceleration = 6 meters/second*second What reached the finish line first? Why?
The sporty vehicle won this time because i
switched the speed and accleration Go to:
