What type of energy transformation occurs when using an electric pencil sharpener?
Heat energy is transformed into electrical energy.
What does a moving object always have energy in?
Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is “stored” because of the position and/or arrangement of the object.
When you feel a deep connection with someone do they feel it too?
Chemistry is the emotional connection that two people feel when they have feelings for each other. Chances are if you are feeling it, they are feeling it too! Chances are, if you feel like there is something special between you and someone else, then that’s a sign of attraction between two people.
Can you touch energy?
Energy is stuff that moves from point to point, as in the Sun radiating light from its atomic fusion. I cannot “touch” your energy, but the result of your energy would hurt me if you rode into me with your bicycle. Thus, energy is an element of momentum, whether is be momentum of light or momentum of matter.
Can all energy be transferred?
Energy can be transferred (move from one location to another) and it can change (transform) from one type to another – but the total amount of energy is always conserved, i.e. it stays the same.
What happens when energy is transferred from one system to another?
Kinetic Energy. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. For the blue ball to move to the position of the green ball, energy must be given to the blue ball.
What machine has the most moving parts?
The timepiece with the most moving parts is the universe itself. It is also the only true “perpetual” one!
What are two ways that machines make work easier?
Background Information. There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied.
Which formula is used for calculating the efficiency?
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.
What is one disadvantage of becoming more energy efficient?
Explanation: The most common hurdle for energy efficiency measures to get over is the cost of implementing a new more efficient technology. However, you will save energy costs over the long-term and this is called “the pay back” period.
What are some pros and cons of energy efficiency?
Pros include less use of energy and generally less greenhouse gases, while the cons are increased cost.
