200
when the force of an object increases so does the what
What is acceleration
300
what is the rate at which velocity changes over time
What is acceleration
300
the unbalanced force that causes objects to move in a circular path
What is centripetal force
300
what is the acceleration of an object depends on the mass of the object and the amount of force applied
What is newton's second law of motion
300
name an example of newton's third law of motion
What is a swimmer propelling him/herself in the water, etc...

what is free fall
What is the motion of a body when only the force of gravity is acting on the body
400
what does the word centripetal mean
What is toward the center
400
true or false the acceleration is always in the same direction of the force applied
What is true
400
do all forces act in pairs
What is yes
400
when an objects acceleration increases what does its mass do
What is decreases
500
what is the constant velocity of a falling object
What is terminal velocity
500
what is newton's first law of motion
What is An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force
500
when an objects acceleration decreases what does its mass do
What is increases
500
what is the pair called when forces act
What is action and reaction
500
does an object with a small mass have more or less inertia than an object with a large mass
