Inertia
What is inertia?
What are balanced forces?
Two or more forces that are equal in magnitude but opposite in direction (cancel each other out, F=0 N)
What are unbalanced forces?
Two or more forces acting on an object to change its state in motion. (F > O N)
What is net force?
The sum of all the forces acting on an object.
What is Mrs.Romero favorite color?
Purple
Give an example of an object with high inertia.
Any object with HEAVY mass.
If two people are pushing a car in opposite directions with the same force, what happens?
The car will remain at rest (F = 0 N)
If one person pushes a car with more force than another person is pulling it, what happens?
The car will have a change in motion in the direction of the person pushing with more force.
How do you calculate net force when two forces are acting in the same direction?
By addition
What college did Mrs. Romero go to?
UTSA
How does mass affect inertia
MORE mass= MORE inertia
How do balanced forces affect the motion of an object?
Balanced forces have no effect on an object's motion. An object at rest will remain at rest.
Explain how unbalanced forces can change the motion of an object.
Net force will be greater than 0 N, which leads to a change in motion.
If a dog is pulling on a leash with a force of 10 N to the right and a child is pulling with 5 N to the left, what is the net force?
F = 5 N right
What is Mrs. Romeros favorite holiday?
Halloween
What happens to an object at rest according to Newton's 1st law?
It will remain at rest until an unbalanced force acts on it.
Give an example of balanced forces in everyday life.
- A ball resting on the ground
- A pencil resting on the desk
- A cup resting on the counter
Give an example of unbalanced forces acting on a skateboarder.
-When they push off to change their motion (speeding up)
-When the wheels experience friction force causing a change in motion (slowing down)
-When they experience drag (air resistance) force causing a change in motion (slowing down)
A lady pushes forward on a door with a force of 10N.
The door opens. What is the net force acting on the
door?
F = 10 N forward
What city/side of town did Mrs. Romero grow up in?
San antonio / Southside
Why is it difficult to push a heavy object compared to a light object?
It has more inertia which resists changes in motion.
What is the net force when forces are balanced?
F = 0 N
What is the net force when forces are unbalanced?
Describe a scenario where multiple forces are acting on an object and explain how to determine the net force.
