True. When radar energy is returned, it can provide information on the direction and speed of raindrops. By analyzing the Doppler shift of the returned signal, meteorologists can determine the speed at which raindrops are moving towards or away from the radar site.
True. When work is done, energy is transferred from one object to another. Work is the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.
False. Electrical energy is the energy associated with electric charge and the flow of electric current. It is not the total kinetic and potential energy of the particles in an object.
False. Balanced forces do not change an object's direction. Balanced forces only keep an object at rest or in a uniform motion in a straight line. If an object changes direction, unbalanced forces are acting on it.
False. The rate at which work is done is called power. Energy is the ability to do work.
False. In a chemical change, other forms of energy, such as heat or light, can be changed into chemical energy. This transformation can occur during reactions where energy is either absorbed or released as chemical bonds are broken or formed.
false
false; you cannot get energy from nothing, it is conserved
FALSE!!
True. When work is done, energy is transferred from one object to another. Work is the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.
"Fraud," or in some jurisdictions, "False Pretenses."
False. Electrical energy is the energy associated with electric charge and the flow of electric current. It is not the total kinetic and potential energy of the particles in an object.
False. Balanced forces do not change an object's direction. Balanced forces only keep an object at rest or in a uniform motion in a straight line. If an object changes direction, unbalanced forces are acting on it.
FALSE.. they are great sources of stored energy!
False
False
False. A stick of unlit dynamite contains potential energy, not kinetic energy. Kinetic energy is the energy of motion, while potential energy is the stored energy an object possesses due to its position or state.
False. The rate at which work is done is called power. Energy is the ability to do work.
