Science Energy Quiz Flashcards
What is the potential to do work?
Energy
What is energy that depends on how fast an object is moving?
kinetic energy
What is energy that depends on the position of an object?
potential energy
What is kinetic & potential energy added together?
total mechanical energy
What is energy that is captured by solar panels?
light energy
What are some forms of energy?
light, heat, magnetic and electrical
How does an objects distance from the ground relate to how much potential energy it has?
The farther an object’s distance from the ground, the more potential energy it has.
What activities require energy?
running, walking, and talking
What activities give us energy?
Sleeping and eating
What energy does a moving car have?
kinetic energy
What energy does a car that is standing still have?
potential energy
How do we know which objects have more energy in terms of speed?
The greater on objects speed the more kinetic energy it has
Two balls, a purple one and an orange one, are pushed across the ground. The orange ball is moving noticeably slower than the purple ball. Which one will roll the farthest?
The purple ball will roll farther and it has more kinetic energy.
Which one has more kinetic energy? Explain your answer.
We know this because the more energy an object has, the farther it will go, the faster its speed.
