Vertical
True or False
Another way of saying Vertical is moving up and down on a coordinate grid?
True, Vertical means to move along the Y-Axis which means going up and down on the coordinate grid.
True of False
Another way of saying Horizontal is moving side to side on a coordinated grid?
True, horizontal means moving along the X-Axis which is left and right on the coordinate grid.
What is considered to be forces in balance?
When 2 forces are equal in magnitude and opposite in direction.
What are the two main types of energy?
Kinetic & Potential Energy
Unit used to measure Force, denoted by the symbol N. Named after the man credited for discovering gravity, named Sir Isaac ______.
Newton
If a block is being pushed down a hill in the positive direction. What force is pulling down on the block in the vertical direction?
The force of Gravity
If a block is being pushed down a hill in the positive direction. What force is moving the block in the positive horizontal direction?
The force pushing the block.
What is the name of the force opposing the force of gravity?
Normal Force
Name the 3 main forms of Potential Energy.
Chemical, Gravitational, and Elastic
The independent or interrelated objects comprising and functioning as a whole.
System
Question on Board
Unbalanced, 30N Right
CFU #5
D. Remove the teacher and replace them with 2 students.
True or False
A car at rest has no forces acting on it.
False, Gravity is constantly pulling down onto the car and the ground is pushing up on the car.
What is the name of the process plants use to convert light energy from the sun into chemical energy?
Photosynthesis
Occurs when the sum of all forces acting on an object are zero, and the forces are equal in magnitude and opposite in direction.
Balanced Forces
CFU #4
A. 117N
CFU #1
B. The horizontal forces are balanced.
If 2 students are playing tug of war, one pulling with a force of 50N and the other with a force of -50N. Which student will win the tug of war?
Neither, the forces are equal in magnitude and opposite in direction.
Name the types of energies in order that go through a flashlight starting with the battery, going through the wire, and finishing on the light bulb.
Chemical > Electrical > Light/Thermal
The sum of all forces acting on an object. We will be focusing on those due to pushes, pulls, and gravity.
Net Force
A baseball player catches a ball that is thrown in the air. What forces are acting on the ball when the ball hits the players glove?
The force of gravity pulling down the ball, the normal force opposing the ball in the vertical direction, the push of the glove onto the ball in the opposite direction it was hit.
CFU #3
B. The horizontal forces are balanced, the vertical forces are unbalanced.
If 2 people are using a rope to play tug of war and student 1 is pulling with a force of 100 N, while student 2 is pulling with a force of -50 N. Which student will be moved?
Student 2 will be moved, -50 N has less force than 100 N and so student 2 will be pulled in the positive direction.
What factors determine an objects Kinetic Energy?
Mass and Velocity/Speed
Forces that are not equal in size or direction and the net forces on an object is not equal to zero.
Unbalanced Forces
