1. Place your fingers along the angle of your jaw just in front of your ear. Grit your teeth and observe what happens to the feel of the muscles in your cheek. Record your
observations.
2. With the thumb and little finger of one hand, span the opposite arm's biceps (front
muscle of the upper arm) from the elbow to as close to the shoulder as possible. Bend the
arm and observe the change in the length of the muscle. Record your observations.
3. Wrap a strip of paper around your brachial region and mark the circumference on the
paper. Move the elbow joint into flexion, tightening the biceps brachii, and mark the new
circumference on the paper. Observe what happens to the circumference of the muscle.
Record your observations.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
