Force vocab Flashcards
Formula used to calculate force
Force= mass•acceleration
Contact force
When 1 object pushes or pulls on another by touching it
Gravity
The force of attraction between two objects
Friction
A force that resists motion between two surfaces that pressed together
Magnetic force
Force exerted between electrically charged moving particles to create a field
Net force
Overall force on an object when all forces are acting on it combined
Balanced force
When two opposite forces are EQUAL then the net force
= 0 newtons
Unbalanced force
When two forces act in the same direction they ADD, and when two forces act unequally inthe opppsite direction they SUBTRACT.
Force
push or pull that causes an object to start moving, stop moving, or change directions.
(vector quantity)
Inertia
The resistance of an object to change
The greater an objects mass, the greater its inertia
First law of motion
Objects at rest stay at rest, and objects in motion stay in motion unless acted on by an unbalanced force.
Newton’s 2nd law of motion
Force=mass•acceleration
Newton’s 3rd law of motion
For every action, there is an equal and opposite reaction
