If you dropped an apple and a feather on the moon at the same time, which will fall first?
What is they will both hit the ground at the same time. (MASS DOES NOT AFFECT MOTION)
100
A pendulum swinging is an example of this type of motion
What is periodic motion?
100
A car and truck are traveling at the same speed, which has more kinetic energy?
Truck (more mass=more kinetic energy)
100
This is the only kind of energy that we can actually see with the naked eye.
What is light energy?
200
A push or a pull
What is force?
200
Which will have more friction, a rougher surface or a smooth surface?
What is rougher surface?
200
A person walking at a steady pace is an example of this type of motion.
What is uniform motion?
200
Where will a roller coaster have the most kinetic energy?
What is at the top of the steepest hill. (the higher an object, the more potential energy it has)
200
This energy is delivered by tiny charged particles called electrons, typically moving through a wire.
What is electrical energy?
300
The force between two objects, and the reason we don't float away!
What is gravity?
300
An object in motion will continue to move at the same speed and in the same direction. What is this called?
What is inertia?
300
A clock ticking is an example of this type of motion.
What is periodic motion?
300
An apple hanging for a tree has this type of energy.
What is potential energy
300
This is energy stored in an object's height. The higher and heavier the object, the more of this type of energy is stored.
What is gravitational energy?
400
If an object has more mass, you will need more _______ to move it.
What is: more force is needed
400
An object at rest will remain at rest and an object in motion will remain in motion. What scientific law is this?
What is Newton's First Law of Motion?
400
A rollercoaster traveling down a steep hill is an example of this type of motion.
What is variable motion?
400
A person walking has this type of energy.
What is kinetic energy.
400
This is energy stored in the bonds of atoms and molecules. This energy is converted to thermal energy when we burn wood in a fireplace or burn gasoline in a car's engine.
What is chemical energy?
500
A force that slows an object down.
What is friction?
500
Energy can neither be created nor destroyed. Only transformed. What law is this?
What is the Law of Conservation of Energy?
500
A car slowing down for traffic is an example of this type of motion.
What is variable motion?
500
Another way to say potential energy.
What is stored energy?
500
This is energy stored in objects by tension. Compressed springs and stretched rubber bands are examples of stored forms of this energy.
