Force
Newton's Laws
Newton's First Law
Newton's Third Law
100
a push or pull that one body/object exerts on another
force
100
For every action there is an equal and opposite reaction force
Newton's third law of motion
100
what force causes an object resist a change in motion and remain unchanged?
Inertia
100
Give one example of Newton's third law of motion
(teacher will decide whether team get the points)
200
the overall sum of all the forces acting on an object
net force
200
An object at rest will remain at rest and an object in motion will continue moving at with the same ______________ and ______________ unless acted on by an unbalanced force
SPEED and DIRECTION (also, Newton's first law ^-^)
200
Give one example of Newton's first law of motion
(teacher will decide if team gets the points)
200
What force is considered the "reaction" in this example.
Action: Person's feet pushes off the wall
Reaction: Wall pushes back on person's feet
300
What happens if the net force acting on an object is zero
The object will not move/change
300
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional its mass
Newton's 2nd law
300
An object that is still will only change if acted upon by an _______________.
unbalanced force
300
Consider the flying motion of birds. A bird flies by using its wings. The wings of a bird push air downwards, causing the bird to fly upwards. What is the action in this example?
the bird pushing air downwards
400
Two/more forces that are equal in size and acting in opposite direction
Balanced force
400
What are all of Newton's Laws Related to?
Motion
400
An object with a lot of inertia is likely to do what
Resist change
400
Newton's third law of motion states that forces always act in __________.
pairs.
500
How do you calculate Net Force
You find the overall sum of all forces acting on the object. (ADD the forces in the SAME direction...SUBTRACT the forces in OPPOSITE directions).
500
The acceleration of an object is ______________ proportional its mass.
INVERSELY
500
Newton's first law is also known as __________________
The law of inertia
500
Newton's third law is also known as the law of _______________.
Action-Reaction
