Practical Problems
Two forces are going the same way,
Unbalanced or Balanced
Unbalanced
100N left
100N right
What is a objects resistance to a change in motion called
(Your launched off a suddenly stopped bike)
Inertia
Push or Pull on an object
Force
Who invented what we're studying in science?
(Newtons first law)
Isaac Newton
If no forces are acting on a object is it balanced or unbalanced?
Balanced
750N > < 545N
205N
What force acts on you when to surfaces rub together.
Friction
What type of force is it when forces cancel each other out
Balanced forces
What happens to an object at rest when net force is zero
It stays at rest
the force going down is 75
the force going right is 90
the force going up is 75
the force going left is 90
Balanced or Unbalanced?
Balanced
47N Right <240N Left
How much N is acting on it
193N
What do you call the total force acting on an object?
Push or pull of an accelerating of an object
Unbalanced Forces
What happens to a moving object when net force is zero
It stays in motion
Say you crash into a trash can and you go flying though your bike stays still.
What is it called when this happens?
Inertia
If a car is pulling a trash bin but it doesn't move at all, how many newtons are acting on it
0N
an object in motion remains in motion at a constant speed in a straight line, unless it is acted upon by an unbalanced or net external force
Newtons first law
What force pulls objects toward earth
Gravity
75N Forward
100 Backward,
50 Newtons Right
Which direction is it going
Bottom-Right
Why is when two forces are going the same way unbalanced?
Because the object is in motion and accelerating.
Can an object stay stationary if 400 newtons of power are pulling it from the right
Yes
(Because 400N of power can be acting on its right)
What force slows objects moving in the air
Air Resistance
What is speed in a specific direction?
Velocity
What makes it why you may need more push or pull on an object?
Mass
