Newton's First Law​

Force - a push or pull that affects an object’s state of motion
Now, you must be wondering, what is force? Force is a push or a pull or any other kind of action that capability to change motion. Force can be used to change the direction of an object or speed up or slow down the rate at which an object is moving. There can be no change in motion without a force. If there is ever to be a change in motion, there must be a force applied.
Emma: I did the text, the video, and the colors on the photo. I also did the coloring on page.
Scarlett: Did the pineapple house on the cover and the base of the drawing. I also worked with Emma to do the video.
Net Force:
The combination
of all the forces
in an object while
gravity is acting upon it.
Net force determines the
motion of an object.
Sofia C.-Did the definition, diagram, and video
Cimone T.-Did the example and the tennis ball
Example: As you hit a tennis ball with your racket, the force and its energy is being transferred from the racket to the tennis ball. This causes the tennis ball to move. The forces acting on the ball are its weight, regular force, and the friction that causes the tennis ball to move. Altogether, these forces make up the net force.
Inertia In the First Law
Inertia means that an object continues to move - or stay in motion at the same speed - unless acted upon by another force, like gravity. In other words, if an object is moving 10 miles per hour to the north it will continue to move at 10 miles per hour to the north because it has inertia.
Vocab Terms
Speed-distance over time or how fast an object is moving
Force- a push or pull on an object
Inertia- the tendency to remain unchanged
Through The Eyes of a New Driver
When you are a new driver, you have to learn how to stop and start your car. You learn that you cannot move the car unless you apply force. If you do not apply force, inertia keeps the car at the same position and the same speed.
I (Jacob) created this Isaac Newton Spongebob on Google Draw that is used on every page.
Emma D. wrote the text and made the car and then Jacob mabe the spongebobs.
Newton's First Law of Motion
​Balanced and Unbalanced forces
This law is referred to as the law of inertia. It states that an object in motion will stay in motion and an object at rest stays at rest ,unless acted upon by an unbalanced force.
Unbalanced force- A force of any sort that changes the motion of an object at any speed by collision.
Example of unbalanced forces:
Balance forces- are two forces acting in opposite directions on an object, and equal in size.
Jonny- Video and definition of unbalanced and balanced forces
In this video, a volleyball is thrown into the air. The volleyball travels at a constant speed until another volleyball collides with the first one and changes the direction and speed of the first volleyball and itself.

Acceleration is the result of unbalanced forces- Newton's Second Law
Writing by: Colin, Video/Red text by: Reid, Picture, script and question by: Aziz
If a car has a force applied on it forward at 10N, and a downward force of 6N, will it accelerate?
Speech Bubble
As the net force increases, so will the acceleration of the car. Because a net force is also an unbalanced force, any unbalanced force will cause a mass to accelerate.
A net force causes a mass to move. This net force is 4 because the friction (2N) minus the velocity (6N) equals the net force (4N).
Acceleration= Force/Mass
When there is an unbalanced force, there will be acceleration. The acceleration of an object depends on the objects mass, and the force that is applied to it.
