Sir Newton
This is the term for a push or pull that can change an object's motion
What is a force?
This is the energy an object has because of it's motion.
What is kinetic energy?
This force always pulls objects toward Earth.
What is gravity?
You are bouncing a ball. At the top of a bounce the ball has mostly this type of mechanical energy.
What is gravitational potential?
It is possible for energy to be destroyed if two vehicles collide.
What is NO?
This is the energy stored because of an object’s position
What is potential energy?
It is impossible to simulate an investigation without this universal force present.
What is friction?
A skateboarder prepares to zip down a steep ramp. She starts at the top of Point A and zips down the ramp to Point B, all the way to Point C at the bottom. Where will she have the most Gravitational Potential Energy?
Where is at the top? (Point A)
If an object moves at a constant speed in a straight line, the net force on it is this.
What is zero? (zero net force)
This letter is used to label the vertical axis.
What is Y?
This is ability to do work or make a change.
What is energy?
A bowling ball and a beach ball book fall from the same height. Which has greater gravitational potential energy before falling?
Bonus: why?
What is the bowling ball has greater gravitational potential energy
(because it has more mass)
This states objects at rest stay at rest.
What is Newton's First Law?
What two quantities are needed to calculate average speed?
What are distance and time?
Adding metal washers to a car, does this to it's potential energy.
What is increases its potential energy.
This is a variable you would keep constant when testing how mass affects kinetic energy using the ramp setup.
What is ramp surface?
Two cars are pushed the same distance with the same force. One car has twice the mass. Which car will have the greater acceleration?
(Bonus= which of Newton's Laws does this explain?)
What is the lighter car?
When the skateboarder rolls down and gains speed, potential energy is converted into this energy.
What is kinetic energy?
This term identifies the change in an object's position and direction.
What is velocity?
Is the formula for calculating velocity.
Bonus: if a vehicle travels 3 meters and the average times is 24 seconds, what is its velocity?
What is d/t?
