Dose a boulder rolling down a hill have potential energy true or false?
True. The boulder rolling down a hill possesses potential energy due to its height above the ground, which can be converted into kinetic energy as it rolls downward.
Dose a heavier or lighter object have a greater kinetic energy?
A heavier object typically has greater kinetic energy than a lighter object. This is because kinetic energy is directly proportional to an object's mass: the greater the mass, the greater the kinetic energy, assuming both objects are moving at the same velocity.
What dose a wind turbine convert?
A wind turbine converts the kinetic energy from the wind into mechanical energy through the rotation of its blades. This mechanical energy is then converted into electrical energy by a generator within the turbine, which can be used to power homes and businesses.
What energy dose a skier has at the top of a hill and coming down a hill?
At the top of a hill, a skier has potential energy due to their position above the ground. As the skier comes down the hill, this potential energy is converted into kinetic energy as the skier gains speed.
When Thinking about putting a glass of water on the counter in the freezer and on a hot stove how dose the temperature of the water affect its kinetic energy and physical state?
The temperature of the water affects its kinetic energy. At higher temperatures, the water molecules have more kinetic energy, resulting in increased movement and thermal energy. When placed in the freezer, the kinetic energy decreases, causing the water molecules to slow down and form a solid state (ice). On the hot stove, the increased kinetic energy causes the water to evaporate and turn into steam (vapor) as it reaches its boiling point.
