What Does it Take to Make an Object Move?
Is Force Needed to Maintain Motion?
Where Is It?/What Keeps Things Moving in a Circle?
What is Velocity?/What is Acceleration?
100
A push or a pull that acts on an object
What is force?
100
A force that opposes the motion of an object moving past another
What is friction?
100
How fast an object's position is changing with time at any given moment
What is speed?
100
A change in velocity
What is acceleration?
200
The tendency of an object to resist a change in its state of motion
What is inertia?
200
Objects at rest remain at this and objects traveling at a steady rate in this line will continue that way until this acts on them
What is rest, line, force?
200
A force that pulls objects to the Earth
What is gravity?
200
The speed of a moving object taken together with its direction of travel
What is velocity?
300
This is why in an experiment a toy car would travel faster than a toy truck
What is because the toy car has less mass and since the truck has more mass it is harder to set in motion?
300
True or False: In space, a force is needed to keep a moving spaceship traveling in a straight line
What is false?
300
True or False: The location of an object is called its position
What is true?
300
Occurs when a force causes the speed of an object to decrease
What is deceleration?
400
This aspect of an object tends to make the object resist being set into motion
What is mass?
400
This is what is not needed and needed to maintain motion at a steady rate if friction is taken away
What is force (not needed) and inertia (needed)?
400
You are moving when you are changing this
What is position?
400
This is how velocity is different from speed
What is because velocity is an object's speed in a certain direction?
500
Forces are needed to set objects in this
What is motion?
500
This is the force that is acting on a sailboat to keep it moving
What is wind?
500
This tells you how fast an airplane is moving
What is shadow?
500
True or False: If the speed of an object does not change but the direction changes, it is accelerating
What is true?
