define force
its a push or pull movememnt that causes an object or body to speed up, slow down, or change direction.
force equation
force = mass x acceleration
how can force affect an object?
- change shape of an object
- move the object
define mass
the quantity of matter found within a particular body, usually measured in kilograms
define inertia
the resistance of a body to change it’s state of motion
define distance
the path travelled from start to finish regardless of direction
define displacement
the difference between initial position & final position of an object
define speed
how fast an object moves
define velocity
how fast an object moves in a specific direction
speed equation
speed = distance/time
velocity equation
velocity = displacement/time
define acceleration
the rate of velocity change experienced by an object over time
acceleration equation
acceleration = final velocity-initial velocity/time
what happens if the velocity increases over time measured?
the object will experience positive acceleration; it speeds up
what happens if the velocity decreases over time measured?
the object will experience negative acceleration; it slows down (deceleration)
what does it mean if there is no velocity change overtime?
the body will be travelling at the same velocity or have stopped; zero or no change in velocity
momentum equation
momentum = mass x velocity
