3) Brittle4) Right side of the zig zag
What is a metalloid?
-Has properties of both a metal and a non-metal-Semi conductor of electricity
What are 4 properties of a metal?
1) Good Conductor of electricity
2) Malleable/Ductile3) High Luster4) Left side of the zig zag
What is the formula for calculating density?
D=m V
If the density of water is 1g/mL, will an object that floats on water be more or less dense than water?
Less Dense
A rectangular block has a mass of 12g and the sides measure 3cm by 2 cm by 1cm What is the density of the object?
D= m = 12g = 2g/cm V 6cm
Find the density of a marble with a mass of 8g using the picture
below:
D= m= 8g = 0.4g/mL V 20ml

________________ ________ ________Electrical Light Thermal Mechanical
Where do we have the most potential energy in the picture? Most kinetic
energy?
Most Potential = 1&5Most Kinetic = 3
What is the formula for calculating speed?
S= d t
If Mandi runs 45m in 5min, what is her average speed?
S= d = 45m = 9m/min t 5min
Samuel ran 50yd in 2min. What is his average speed?
S = d = 50yd = 25 yd/min t 2min
In 3hrs a motorcycle traveled 360mi. What is the motorcycle’s
average speed?
S = d = 360mi = 120mi/hr t 3hrs
What was the average speed of Car 1 at 45 seconds?
S= d = 100cm = 2.2cm/sec t 45sec
What was the speed of car 2 at 120cm?
S= d = 120cm = 2.6 cm/sec t 45sec
Look at the graphs below: Place them in order from slowest to fastest
according to their speed.
