Q: What term is not the same as energy, but means the energy per unit charge? Read this paragraph and choose the correct option from the provided answers: The second equation is equivalent to the first. Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since PE = qV . The car battery can move more charge than the motorcycle battery, although both are 12 V batteries. Choices: - frequency - speed - mass - voltage A:
**Answer**
voltage

Q: What is the measure of the force of gravity pulling down on an object called? Read this paragraph and choose the correct option from the provided answers: Weight is a measure of the force of gravity pulling down on an object. Buoyant force pushes up on an object.
