Question 2
The two main forms of mechanical energy are:
- Aheat and light
- Bpower and work
- Ckinetic and potential
- Dforce and mass
Show answerHide answer
Answer: C
Kinetic and potential energy are the two kinds of mechanical energy.
Question 3
Kinetic energy is the energy possessed by a body due to its:
- Aposition
- Bmotion
- Cshape
- Dtemperature
Show answerHide answer
Answer: B
A moving body can do work because of its motion.
Question 4
Potential energy is the energy possessed by a body due to its:
- Amotion
- Bspeed
- Cchanged position
- Dangular velocity
Show answerHide answer
Answer: C
Potential energy is stored by virtue of a changed position or state.
Question 5
The kinetic energy of a body of mass m and speed v is:
- Amv
- Bmv²
- C½mv
- D½mv²
Show answerHide answer
Answer: D
Derived from the work done by friction in stopping the body: K.E. = ½mv².
