Total questions: 18
Worksheet time: 54mins
Look closely at the table. Which variable is being controlled (kept the same) in each game of table tennis?
Type of Sports Ball
Speed (m/sec)
Mass (grams)
Kinetic Energy (Joules)
An independent variable is the variable that can be changed (manipulated) by the researcher for each trial of the experiment. Which of the following numerical choices can be changed by the researcher during each trial?
Type of Sports Ball
Volume (cm3)
Mass (grams)
Kinetic Energy (Joules)
Look carefully at the graph for this question. The graph shows the Kinetic Energy of bike riders moving at different speeds. Each rider has a mass of 60 Kg. Estimate the amount of Kinetic Energy (in Joules) for a rider moving at 22 m/s.
(a)
Use the data you have recorded in your POGIL packet to help answer this question:
Listed below are several different types of Sports Balls. If each ball is hit at 20 m/s, reorder the Sports Balls in order from Smallest Kinetic Energy to Greatest Kinetic Energy.
Ping Pong Ball
Hard Foam Ball
Solid Rubber Ball
Golf Ball
Super Ball
The graph shown on the left represents the graph that you should have created during your group work for this POGIL. The graph shows the Kinetic Energy of different sports balls with different masses. Estimate the Kinetic Energy (in Joules) for a ball with the mass of 50 grams.
(a)
Look closely at the model. Which variable(s) are not being controlled (kept the same) in the ride?
Type of Riding
Total Mass of bike + rider system
Speed of bike (m/s)
Reorder the following types of riding from greatest amount of Kinetic Energy to least amount of Kinetic Energy.
Sprinting
Commuting
Casual
Waiting
Track Racing
Look closely at the model to the left. Which factor is being kept constant (controlled or kept the same)?
Type of Riding
Total Mass of bike + rider system (kilograms)
Speed (m/sec)
Kinetic Energy (Joules)
The graph represents the data you should have graphed during the POGIL activity. Based on the graph, estimate the Kinetic Energy of a rider moving at 20 m/s.
(a)
Use the provided data tables to answer the following question:
Which variable has a greater impact on an object's kinetic energy?
the speed of an object
the mass of an object
both speed and mass have the same effect on an object's kinetic energy
neither speed or mass have an effect on an object's kinetic energy

A bicycle speeds up as it moves along a flat road. What happens to the bicycle’s kinetic energy during this time?
It decreases.
It increases.
It remains the same.
The diagram shows a block sliding along a frictionless (slippery) surface between points A and G.
As the block moves from point A to point B, the kinetic energy of the block
decreases
increases
is constant, but not zero
is zero
If the speed of an object is doubled, its kinetic energy will
increase
decrease
remain the same
