2.2 LAB Assignment Spring Propelled Projectile

LAB Assignment: Spring Propelled Projectile Student Name: Record the values observed or provided in the video and do the calculations. When two fields are provided for a quantity, the number part of the answer goes into the first field and the units in the second field. Example: Quantity Unit How many centimeters in 1 meter: 100 cm Quantity Unit Mass of Ball Bearing (m) 16.3 G Compression displacement for 1 click (d 1 ) 4.4 cm Height ball reaches (vertical displacement) (h 1 ) 45 cm Compression displacement for 2 clicks (d 2 ) 5.7 cm Height ball reaches (vertical displacement) (h 2 ) 75 cm Compression displacement for 3 clicks (d 3 ) 7.2 cm Height ball reaches (vertical displacement) (h 3 ) 120 cm When converting units, never round any numbers. Example: 1.23 cm = 0.0123 m, not 0.01 m or 0.012 m. There are 1000 g in 1 kg and 100 cm in 1 meter. Convert Mass of ball bearing to kg. (m) .0163 kg Convert all the distances from cm to m. Quantity Unit Compression displacement for 1 click (d 1 ) .044 m Height ball reaches (vertical displacement) (h 1 ) .45 m Compression displacement for 2 clicks (d 2 ) .057 m Height ball reaches (vertical displacement) (h 2 ) .75 m Compression displacement for 3 clicks (d 3 ) .072 m Height ball reaches (vertical displacement) (h 3 ) 1.20 m When doing calculations below, always use the quantity in standard metric units ( kg for mass, meters for distance). Calculate the Gravitational Potential Energy for each trial. Remember that weight ( W ) and mass ( m ) are not the same thing in physics. Do not round these values.
