Question

mark as true or false:

1. driving on ice can be dangerous.
2. wheels increase friction between the road and car machinery.
3. banana peel reduces friction between you and the ground.
4. friction converts kinetic energy into heat energy.

Explanation:

1. Ice reduces friction between tires and road, making driving dangerous - True. Ice is slippery and lowers friction.
2. Friction between wheels and machinery is often beneficial for operation and is not always just about increasing - False. While friction can be useful for grip in some cases, this statement is too simplistic as excessive friction can cause wear and energy loss.
3. A banana - peel reduces friction between you and the ground, making you more likely to slip - True. The peel acts as a lubricant, decreasing friction.
4. Friction converts kinetic energy into heat energy - True. This is a fundamental property of friction, as work is done against it and energy is dissipated as heat.

Answer:

1. True
2. False
3. True
4. True
