My Bike Flashcards
acceleration
change in velocity / time
attract
to pull with physical force
balanced forces
the forces are the same size but are acting in opposite directions
repel
to push away with force
mass
the amount of matter in an object
energy
ability to do work
force
anything that causes a change
velocity
speed in a given direction
speed
distance / time
deceleration
a term that is used for motion that involves slowing down
electrostatic force
the forces between particles that are caused by their electric charges
unbalanced forces
can make objects start to move, speed up, slow down, or change direction
force diagram
is a diagram showing all the forces acting on an object, the force’s direction and its magnitude
force field
an invisible barrier of force
friction force
two surfaces that are sliding or trying to slide across eachother
gradient
the amount if rise or fall from a start point to a finish point
gravity
is a force which tries to pull two objects toward each other
lubricant
a substance used for lubricating an engine or component, such as oil or grease
magenetism
when two energy fields are attracted to eachother
Newton
the measure of force
North Pole
where the lines of the forces of the earth’s magnetic field are vertical
reaction time
the time taken to react after something happens / starts
SI unit
any of the basic units in the international system of units
South Pole
