A stock’s price has been steadily increasing for several months. What might this indicate about investor confidence and company performance? Provide reasoning.
Low confidence and poor performance
High confidence and good performance
No change in confidence or performance
High risk and low return
A lever is used to lift a heavy rock. Explain how changing the position of the fulcrum affects the effort needed to lift the rock.
Moving the fulcrum closer to the rock decreases the effort needed
Moving the fulcrum farther from the rock increases the effort needed
The fulcrum position does not affect the effort
Moving the fulcrum to the center always makes it easier
A roller coaster car is at the top of a hill and then descends rapidly. Describe the changes in kinetic and potential energy during this process.
Kinetic energy increases, potential energy decreases
Both kinetic and potential energy increase
Kinetic energy decreases, potential energy increases
Both kinetic and potential energy remain constant
A company pays regular dividends but suddenly stops. What could this signal to investors, and why?
The company is growing rapidly
The company may be facing financial difficulties

Chemical to electrical
Potential to kinetic
Kinetic to potential
Sound to thermal
You are designing a system to lift heavy objects using the least amount of effort. Which combination of simple machines would be most effective, and why?
Lever and pulley, because they both reduce the force needed
Wedge and screw, because they increase friction
Inclined plane and wheel, because they increase speed
Pulley and wedge, because they store energy
