Units of force in physics
A 100
What are Newtons?
A 200
A force that will work against
motion in everysituation is :
What is friction?
A 200
A 300
During a tug-of-warcompetition, neither
teamis able to gain an advantage this is
because the forces are _____________
What is balanced?
A 300
A 400
This is the amount of force needed to hold the
1kg object pictured.
What is 5.1 N?
[the spring scale reads 5.1,
Spring scales measure force]
A 400
Forces work in equal but opposite:
_______________
A 500
What are pairs?
A 500
B 100
These types of energy are produced by a light bulb.
What is light and
thermal energy?
B 100
[Light bulbs light up and get hot]
B 200
If an object is falling, the acceleration is due to
___________
What is gravity?
B 200
B 300
This type of energy transformation occurs
if a rock sitting on a ledge begins to fall toward the ground.
What is potential energy to kinetic energy?
B 300
B 400
This is the law that states that energy can neither be gained or
lost, only change form.
B 400
What is the Law of
Conservation of Energy?
B 500
Both of these diagrams show this type of energy
transformation.
B 500
What is chemical energy to mechanical
energy?
[both use chemical fuel for movement]
C 100
This piece of science equipment is used to find
the mass of an object.
What is a triple beam balance?
C 100
C 200
This piece of science equipment is used to find the weight or force of an
object.
What is a spring scale?
C 200
C 300
This is the acceleration due to gravity in Earth
C 300
What is 9.8 m/s2
DAILY DOUBLE
C 400
DAILY DOUBLE
Place A Wager
C 400
Estimate the weight in Newtons of a 50 kg
person.
C 400
What is about 500 N?
Using Newton’s 2nd Law formula: F=maWeight= mass x acceleration due to gravity
Weight = 50 kg x 9.8 m/s/sWeight = 50kg x 10m/s/s
Weight = 500 N
C 500
Gyrocopter
This is calculated by measuring the distance
traveled and dividing by the amount of time that is needed
to travel that distance
C 500
What is average speed?
D 100
The Law of Force and Acceleration is recognized by this
formula.
D 100
What is F=ma?
D 200
According to Newton’s 3rd Law of
Motion, forces act in equal but
___________ pairs.
What is opposite?
D 200
D 300
This Law of Motion shows the
relationship between mass and force.
D 300
What is the Law of Force and
Acceleration?
D 400
A person in a head-on car collision who is not wearing a seat belt continues to move
forward at the original speed of the car because of
______________
What is inertia?
D 400
D 500
Newton’s Law of Inertia says “objects in motion stay in motion
unless acted on by an outside force.”
Objects in the back seat of a car would move this
direction if the car suddenly stopped.
What is forward?
D 500
E 100
.This Law of Motion best explains why you may lean sideways in a car if the driver turns a corner too quickly.
What is the Law of Interia?
[Newton’s 1st Law]
E 100
E 200
A rocket is traveling in space at 10,000 m/s.
If no outside force is applied to it,
this will happen to its speed over the course of the trip.
What is stay the same?
[or stay constant]
E 200
E 300
The air friction acting on a baseball causes it to
curve as it is pitched to the catcher. This is an example of Newton’s
Law of ________________
What is inertia?
E 300
[Objects in motion remain in motion unless acted on by an outside force.
Here, the outside force is gravity causing the ball to curve down.]
E 400
You are riding in a car that has a coffee cup sitting on the dashboard.
The vehicle makes a sudden stop to avoid hitting the car
that has stopped in front of it.
This would happen to the coffee cup.
E 400
What is move forward
[until it hit the windshield]
E 500
Jumping on a skateboard and watching the
skateboard move away from you is an example of
this Law of Motion
What is Action-Reaction?
E 500
F 100
The two forces in a force pair are the
____________ force and the _____________
force.
F 100
What are action and reaction?
F 200
This is the point on the roller coaster above with the greatest gravitational
potential energy.
F 200
What is point Y?
[the highest point on the roller coaster has the greatest
gravitational potential energy]
F 300
Balanced or Unbalanced Force
Tectonic Plate Movement(Earthquake)
What is an unbalanced force?
[Unbalanced forcescause movement]
F 300
F 400
This law of motion explains why when you jump
upward, you slow down and eventually fall back to
Earth.
F 400
What is the Law of Force and Acceleration?
[acceleration due to gravity causes you to fall back to Earth. This is also known
as your weight.]
When two continental plates collide, a mountain chain is created between them.This law of motion would BEST describe
why the mountain chain is created.
