P6 Energy

Which of the following explains the movement of the ball?

• The ball moved up as it has more potential energy.

• The ball moved up and down as wind was produced when the drum was hit.

• The ball moved up as kinetic from the drum was transferred to the ball.

• The ball moved up as the kinetic energy from the stick was converted to heat energy on the drum.

• Kinetic energy → potential energy → kinetic energy

• Potential energy → kinetic energy → heat energy + sound energy

• Kinetic energy → potential energy → heat energy + sound energy

• Potential energy → heat energy + sound energy → kinetic energy

• The loudness of the sound produced is definitely 45 units when a 3 kg ball is dropped at 30 cm.

• A ball with a smaller mass produce a louder sound when dropped from the same height.

• A ball with a larger mass dropped at a greater height will have all of its potential energy converted to sound energy.

• A ball that is dropped from a greater height will produce a louder sound than the same ball dropped from a lower height.
