Newton's First Law Activity
If so instructed by your teacher, print out a worksheet
page for these problems.
Open the slide called
Newton's First Law (with
text). Study the labeled diagram and read the explanation of the Newton's
First Law of motion
- An F18 Hornet
aircraft sits motionless on a runway because of inertia. If that plane
starts to move down the runway, it means that there must be a force
acting on it. Of the four main forces that act on aircraft, which one
is most likely to cause the forward motion down the runway?
- Which of the four
forces causes the airplane to become airborne?
- Once the F18 Hornet
is airborne, which force is equal to the force of thrust?
- As the F18 Hornet
travels at constant velocity, it burns fuel, which decreases its weight.
In response to this decrease, which of the four forces is also likely
to decrease?
- On the line below,
draw the arrow that indicates thrust force of the F18
Hornet pictured above:
- On the line below,
draw the arrow that indicates lift force of the F18 Hornet
pictured above:
- On the line below,
draw the arrow that indicates weight force of the F18
Hornet pictured above:
- On the line below,
draw the arrow that indicates drag force of the F18 Hornet
pictured above:
- Which one word
defines Newton's First Law of Motion?
Consider the situations
below to determine whether or not there is an external force acting on
the airplane. Remember that according to Newton's First Law, a plane will
resist a change in its state of rest or motion unless it is acted
on by a force. Write the word force next to the situations
where an external force acts.
- The F18 is flying
at 200 mph at an elevation of 30,000 ft.
- The F18 turns northeast
at 200 mph and an elevation of 30,000 ft.
- The F18 increases
its speed to 220 mph at the same elevation.
- The F18 continues
flying at 220 mph at 30,000 ft.
- The F18 drops to
an elevation of 28,000 ft.
- The F18 heads due
east maintaining its speed and elevation.
