Answer;
The above statement is True
Kinetic friction is affected by the weight of the object.
<h3><u>Explanation;</u></h3>
- Kinetic friction is a force that acts between moving surfaces. An object that is in motion over a surface experiences a force in the opposite direction to the direction of movement.
- The equation for kinetic friction is given by the formula;
F= coefficient of friction * Normal force.
- Normal force is the force of the table pushing back on the block and can be calculated by formula;
F = mass* acceleration due to gravity.
- Therefore, the weight of an object determines its kinetic friction.
Answer:
has more energy, has a greater amplitude, has a higher frequency
Explanation:
Your body loses heat to the water faster than it loses heat to the air. Water has a higher heat capacity, so it is better at extracting heat than air is.
