100
The resistance to motion created by two objects moving against each other
What is friction
100
What are some things that can cause friction to increase or decrease?
What is 1) the type of surface of the two objects in contact 2) how hard they are pressed together
100
The energy of motion
What is kinetic energy
100
A change in an object's position
What is motion
100
True or False - the more massive an object - the less effect a given force will have on an object
What is True
200
the force that pulls objects toward each other
What is gravity
200
What two things determine the force of gravity between objects?
What is mass and distance
200
Stored energy
What is potential energy
200
An object's position related to another object nearby
What is relative position
200
A unit of measure for force.
What is Newton (it is named after Sir Isaac Newton)
300
The amount of material in an object
What is mass
300
How are mass and weight different?
What is the mass of an object stays the same unless something is added or taken away. Weight changes depending on the force of gravity.
300
What are some things that cause kinetic energy to increase or decrease?
What is kinetic energy can be increased or decreased depending on an object's mass and speed
300
A way to describe how fast an object is moving
What is speed
300
Any push/ pull that causes an object to move, stop, change speed/direction
What is force
400
A measurement of a gravity's effect on an object's mass
What is weight
400
True or False. You would weigh the same amount on Earth as you would in space were there is no gravity.
What is False
400
Examples of kinetic energy
What is 1) Roller skating down a hill 2) Dribbling a soccer ball 3) Running a mile 4) Anything that is moving!
400
A measurement of an object's speed and direction
What is velocity
400
What do you need in order to be able to calculate the speed of an object?
What is 1) The distance AND 2) The time it took to travel that distance
500
True or False - Acceleration is only an increase in speed, not a decrease in speed.
What is False. Acceleration can be a decrease as well.
500
True or False - the greater the force, the greater the change in motion will be.
What is True
500
What are examples of potential energy?
What is 1) A pitcher winding up to throw a ball 2) A child at the top of a slide 3) A stretched rubber band 4) Anything that is ready to move!
500
A change in speed or direction of an object's motion
What is acceleration
500
What is the difference between contact force and non contact force? Describe balanced and unbalanced forces?
What is 1) A contact force is one that must TOUCH an object to effect it; non contact forces can effect from a distance (gravity) 2) Balanced forces are equal forces; unbalanced forces are unequal forces
