Patterns of Motion & Friction

a weight tied on a string that swings back and forth

something you write with

a musical instrument

friction

inertia

electricity

force

the friction between the two sticks produces heat

because they are made of wood and wood burns

the fraction between two sticks creates a whole piece big enough to burn

a layer of air that reduces friction is created and pumped through tiny holes in the table

a layer of oil is rubbed on the puck to make is slide better

the puck is actually magnetic and it repels against table

sand paper

grease

oil

banana peel

true

false

airplanes

air hockey

melting ice cream

a ball sitting in a field

each individual block swings back and fourth

all the blocks swing in the same direction at the same time

the blocks all stop moving at the same time

they don't move

each block has different lengths of string so they swing at different speeds.

each block as the same length of string so they all swing together at the same speed

each block has different lengths of string so they all swing at the same speed.
