What is an unbalanced force?
A netting force acting on an object causing the object to change its motion.
Example of an unbalanced force?
Tug-A-War(one group pulling a another group closer to the center).
What is a balanced force?
Equal forces acting on an object which causes no change in the object's force.
Example of a balanced force?
Two people of equal weight on a seesaw.
What is a net force?
The overall force on an object
Both are forces (push or pull)
What do unbalanced and balanced forces have in common?
What are the differences between balanced and unbalanced forces?
A balanced force no active netting force but an unbalanced netting force doesn't. Also a balanced force is equal, an unbalanced force isn't. Plus, an unbalanced force changes an object's motion unlike a balanced force.
What is inertia?
An object wants to keep doing what it's doing. [An object at rest wants to stay at rest, and object in motion wants to stay in motion.]
Force= Mass x Acceleration
What is the EQUATION for Newton's second law of Motion?
What does the newton measure?
The force required the accelerate 1kg of mass at 1m per second (1m/s2)
Increases
As temperature increases, the vapor pressure of a liquid _______.
Decreases
A freight car moves along a frictionless level railroad
Acceleration x Mass
The net force on an object is equal to its...
Acceleration= Force/ Mass
What is the equation for determining acceleration of an object is?
The value for acceleration increases if...
The force increases or if the mass increases.
Example of inertia?
If you're in a car that slams on its brakes... you will move forward until a force acts on you- the seat-belt.
What is Newton's First Law of motion?
An object at rest will stay at rest and an object in motion will stay in motion unless acted upon.
What is Newton's Second Law of motion?
The greater the mass of an object, the greater the force required to move that object.
What is Newton's Third Law of motion?
For every force/action there is an equal and opposite reaction by another force.
Explain Newton's 1st Law?
As long as the forces acting on an object are balanced, the object does not change its motion.
Force= Mass x Acceleration
What is the Equation for Newton's 2nd Law?
Unit of mass is kg
What are the units of force?
Why forces come in pairs
What does Newton's Third Law of Motion explain?
Examples of Newton's Third Law?
Rowing a boat (The water pushes u back as u push forward)
