Lesson 1 - Motion
the exact place an object is
position
to tell what will happen in the future
predict
an act between objects that are touching
contact force
when two forces are equally strong, no motion happens
balanced forces
the way an object faces
direction
What are some patterns of motion you observe in your daily life?
EX: swings going back and forth, seesaw going up and down, a ball rolling when you push it, hands of a clock going in a circle, ect.
a pulling force that stretches something
tension force
the sum of forces acting on an object
net force
any time an object's position changes
motion
If a swing is moving back and forth in a consistent pattern, how can you use the pattern to predict its motion?
By observing the pattern of the motion, I can predict how the swing will move next.
a force that goes against the motion of an object
friction
a change in motion happens
how far something travels
distance
A ball bounces to a certain height when it is dropped from your hand. What will the ball do if it is dropped from a second floor window?
a noncontact force that acts between any two objects that pulls them toward one another
gravity
how slow or fast something can move
speed
identify the forces that are acting on a boy who is being pulled by a dog on a leash.
Tension force on the leash pulls the boy
gravity holds the boy on the ground
