Question

select all the variables that affect the potential energy of an object.
pe = mgh
speed
velocity
gravity
mass
height

Explanation:

Step1: Analyze the formula

The formula for potential energy is \( PE = mgh \), where \( m \) is mass, \( g \) is the acceleration due to gravity, and \( h \) is height.

Step2: Check each variable

• Speed: Not in the formula \( PE = mgh \), so it does not affect potential energy.
• Velocity: Not in the formula \( PE = mgh \), so it does not affect potential energy.
• Gravity (\( g \)): Present in the formula \( PE = mgh \), so it affects potential energy.
• Mass (\( m \)): Present in the formula \( PE = mgh \), so it affects potential energy.
• Height (\( h \)): Present in the formula \( PE = mgh \), so it affects potential energy.

Answer:

Gravity, Mass, Height.
