Calculate the speed if Mr. Oliver does the Harlem shake 200.0 meters down the hallway in 10.0 seconds. Use 3 steps Remember speed = distance/ time
1. s= d/t 2. s= 200.0m/10.0s 3. s= 20.0 m/s

Define genotype and phenotype
genotype- genetic make-up of an organism (the alleles, like Tt TT tt) phenotype- the physical appearance of the trait

Draw an unbalanced force
must equal anything but 0 Newtons
