Kinetic Energy
Two objects have the same speed, but one has more kinetic energy because of this difference.
What is mass?
A book resting on a table has no stored energy.
What is false?
(Because it still has stored energy relative to the floor.)
This stays the same for an object no matter where it is in the universe.
What is mass.
What is Kinetic Energy?
The freezing point of water on the Celsius scale is this number.
What is 0 degrees?
This formula is used to calculate the kinetic energy of a moving object.
What is KE = 1/2 (m*v2)
This is required for an object to have gravitational potential energy.
What is height (or being above the ground)?
This scientist is famous for discovering gravity after an apple fell.
Who is Isaac Newton?
Units for acceleration and speed.
What is m/s/s for acceleration and m/s for speed.
This layer of Earth is made of hot, melted rock.
What is the mantle?
Using the kinetic energy formula, which object has more energy: a 10-kg object moving at 5 m/s, or a 5-kg object moving at 10 m/s?
What is the 5-kg object moving at 10 m/s?
This energy conversion occurs the moment a raised object begins to fall.
What is gravitational potential energy changing into kinetic energy?
If a person travels from Earth to Jupiter, this property of the person increases due to Jupiter’s stronger gravity.
What is their weight?
A runner changes direction but maintains the same speed. T/F, The runner's acceleration is 0.
False.
This gas makes up most of Earth’s atmosphere.
What is nitrogen?
This science law explains why kinetic energy doesn’t just disappear when an object stops.
What is the Law of Conservation of Energy?
This object has more stored energy: a 2-kg book 3 meters high or a 1-kg book 6 meters high.
What is neither — they have the same amount?
The acceleration due to gravity on Mars if Mars is 0.39g.
What is 3.822 m/s2
A ball is dropped from a certain height. Explain in detail what happens to its energy as it falls to the ground. Include what types of energy are involved and how they change during the fall.
As the ball falls, its gravitational potential energy decreases while its kinetic energy increases.
This type of rock forms from lava or magma.
What is igneous rock?
This kind of motion does NOT involve kinetic energy.
What is no motion (or being at rest)?
An object at the same height on the Moon would have _________ stored energy compared to on Earth because of this.
What is LESS stored energy because of lower gravity.
An object has a mass of 20kg on Earth. Saturn has a much stronger gravitational pull that Earth at 1.32g. What would the mass of the object be if it was on Saturn?
What is 20kg
