Meter
an SI unit of distance, abbreviated m; equal to approximately 39.37 in
speed
the distance traveled divided by the time taken to travel that distance.
average speed
the total distance traveled divided by the total time taken, typically expressed in meters per second (m/s).
instantaneous speed
the speed of an object at a specific moment in time, measured in meters per second (m/s).
velocity
the speed of an object and the direction of its motion
kilogram
SI unit of mass, abbreviated kg; equal to approximately 2.2 lbs
acceleration
the change in velocity divided by the time it takes for the change to occur
triple beam balance
scientific instrument used to measure mass precisely by comparing the mass of a sample to known masses
mass
the amount of matter in the object
inertia
the tendency of an object to resist changes in its state of motion
momentum
measured of how hard it is to stop
law of conservation of momentum
states that the total momentum of objects that collide is the same before and after the collision.
