What is a BALANCED force? BE SPECIFIC WITH THE DEFINITION
when TWO forces are EQUAL in strength but act in OPPOSITE DIRECTIONS, canceling each other out & resulting in NO MOTION
A soccer ball is kicked by Manuel and it starts rolling across the field. The ball accelerates as it rolls. Balanced or unbalanced? Explain your answer.
Unbalanced because Manuel's exerted force must of been stronger than the ball's causing it to move across the field
Angel, Emmanuel and Matthew were arguing about who is stronger. Angel said, "I think Emmanuel and I are stronger than you Matthew!" Matthew was upset and suggested that they should go 2 v 1 in a tug-of-war game. Angel and Emmanuel were pulling the rope with a force of 400 N to the west. Matthew was pulling the rope with a force of 650 N to the east. Who is stronger? How do you know? Explain?
Matthew is stronger than Angel and Emmanuel because he exerted 250 N more so the movemment would go to the right, towards Matthew
In natural selection, this is the agent that "selects" for or against traits of an organism.
the environment!
how tall is Lebron James?
6'9"
What is an UNBALANCED FORCE? Be specific with the definition
when ONE force is STRONGER than the other, causing the object to accelerate in the DIRECTION of the STRONGER force
True or False: A car that is moving at a constant speed on a straight road is experiencing balanced forces. Explain your answer.
TRUE: When the car is moving at a constant speed in a straight line, there is no change in its motion (it is not accelerating)
Victor, Eddie and Damien were trying to move a statue of Lebron James into their garage. They figured that with the strength of THREE boys they would be able to get the statue to move. Damien exerted a force of 200 N to the east, Victor exerted a force of 278 N to the east, and Eddie exerted a force of 189 N to the east. What is the net force and what direction is the statue being moved?
667 N to the east ( right)

How would you explain what frame of reference is?
how one knows if an object is moving
a perspective that one uses to determine if an object is moving.
