If a ball has 50 N of force pushing from the left and 25 Newtons of force pushing from the right, what is the motion of the box?
The amount of force and the direction of the force acting on the box.
gravity
There is a net force of 25 N to the left. The box will move to the left.
Friction is produced when objects slide past one another.
change in direction only
The forces are exerted on different objects so they are not balanced forces.
distance and time
You can tell because the opposite forces will be different. Ex. 50 N up and 25 N down
A soccer player kicks a ball. According to Newton’s third law of motion, the player’s foot exerts a force on the ball. The ball exerts a force on the foot. Why don’t the forces cancel out to result in a net force of zero?
The amount of force and the direction of the force acting on the box.
gravity
There is a net force of 25 N to the left. The box will move to the left.
Friction is produced when objects slide past one another.
change in direction only
