Energy
The ability to do work.
Energy
A force is...
A push or a pull.
A change in an object's position.
Who is the science technician who helps us with our inquiry experiments?
Mrs. Fazia
This occurs when two or more objects hit each other with a force.
Collision
What type of energy does a ball have if you are holding it above the ground?
Potential energy
Pushing a child on a swing is an example of a _____________ force.
contact
What is the difference between speed and velocity?
Velocity includes the direction of an object, as well as speed.
How did the mass of the water bottle affect the distance the plastic cup moved?
The more mass, the more the cup moved. The less mass, the less the cup moved.
This is Mrs. Carly's three favorite foods.
Mexican food, sandwiches, popcorn:)
A roller coaster going down its first drop has converted its potential energy into...
Kinetic energy
A force between two objects.
Friction
The tendency of an object in motion to stay in motion.
Inertia
During an experiment, it is important to keep everything the same during all the trials. The thing you are changing is called a _____________.
Variable
The law that states that energy cannot be created nor destroyed.
The law of conservation of energy.
As the height of an object increases its ______________ energy increases as well.
__________ forces change the motion of an object.
Unbalanced
How do we use arrows to show the strength of a force in a diagram?
Draw a longer arrow to represent great force and a shorter arrow to represent lesser force.
What are two things you observed during the Toy Car Crashes Inquiry Activity?
Acceptable examples:
The car moved faster when the height increased.
The car moved slower when the height decreased.
When the cars collided, one car slowed down and changed direction. The other car sped up and changed its position.Ms. Annemi is from a country on this continent.
Africa
During a collision, kinetic energy can be transformed into two different types of energy.
Heat and Sound
A noncontact force that pulls objects towards the Earth.
Gravity
A change in velocity over time.
Acceleration
During the ping pong ball/golf ball inquiry, which ball hit the ground first?
If done properly, both balls should have hit the ground at the same time due to the same air resistance force acting on both balls.
What equation can be used to determine the speed of an object?
Distance/Time=Speed
