N
What is an objects weight
proportional to? MASS
What type of force must What
type of friction do you have to
overcome to start an object in
motion?
STATIC FRICTION
Complete this phrase
For every action there is
AN EQUAL BUT OPPOSITE
REACTION
How do unbalanced forces
cause objects to accelerate?
(2Ways)
CHANGE IN DIRECTION OR
SPEED
What is the upward force on an
object falling through the air?
AIR RESISTANCE
What force causes objects to
slow down?
FRICTION
What is a force that opposes
motion?
FRICTION
What is centripetal force?
TRAVELS IN A CIRCLE LIKE
AN ORBIT
What does Newton’s second law
allow scientists to calculate?
FORCE, MASS, ACCELLERATION
Identify Newton’s law for
swinging a ball on a string
around your head.
NEWTON’S SECOND LAW
Identify Newton’s law that
describes a girl pushes a sled and
the sled accelerates.
NEWTON’S SECOND LAW
Whenever an object exerts a
force on another object, the
second object exerts a force of
the same magnitude. What
direction does the force go?
OPPOSITE
Which law states the relationship
among force, mass, and
acceleration?
NEWTON’S SECOND LAW
When is something a contact
sport?
WHEN THERE IS A
COLLISION/TOUCH
Identify Newton’s law that
describes gravity causes a ball to
fall.
NEWTON’S FIRST LAW
G
O
Explain how to calculate net
force.
IF THE FORCE APPLIED IS GOING
THE SAME DIRECTION YOU ADD
IT. IF THE FORCES ARE OPPOSING
YOU SUBTRACT THEM.
What is the formula for Newton’s
second law?
F=MA
What action is required for a force
to be considered a contact force?
TOUCH
What would happen to the ball if
gravity did NOT affect the path of
a horizontally thrown ball?
GO HORIZONTALLY
Why do astronauts in space
weigh less than they do on Earth?
FURTHER FROM THE
GRAVITIONAL PULL
Identify Newton’s law that
describes a balloon flies off when
the opening is released.
NEWTON’S THIRD LAW
What is the unit for force?
NEWTON
What are forces that are equal in
size but opposite in direction?
BALANCED
How are mass and weight related?
PROPORTIONAL
Identify the law that that describes
a book sitting on the table.
