they do not change motion
Which would you have to apply more force to in order to slide it across the room?: a box of 30 lbs. of textbooks or a box with 60 lbs. of textbooks?

how fast the position of an object changes with time at any moment

The greater the FORCE applied to an object, the greater the_____________
Acceleration
he speed of a moving object taken together with its direction of travel
Velocity
what is Mass?
A measure of the amount of matter in an object. The mass of an object is related to the force required to accelerate it.
What does Trey keep asking to watch in class?
Power Rangers
the more force you apply, the _______ the acceleration
greater
The more MASS an object has, the greater the ________ required to change its motion!
Force
a change in velocity
Acceleration
what is balanced forces?
when all the forces on an object cancel each other out, you have balanced forces – no acceleration, no momentum
what club is Ms.Bergmann teaching?
Drama Club!
when forces don’t cancel each other out, there is movement
unbalanced forces
the tendency of an object to resist a change in motion
inertia
formula for calculating speed
speed = total distance traveled / time taken
what is momentum?
how difficult it will be to stop an object
A force that acts in the opposite direction of the motion of the object
Friction
An object in motion will stay in motion and an object at rest will stay at rest UNLESS ____________________.
acted upon by an unbalanced force.
distance formula
distance = speed x distance
what is action?
when one object applies a force to another object
what is Kenzie's turtle's name?
