Discovered the Laws of motion

Who is Sir Isaac Newton?

100

A push or a pull exerted on an object is called this.

What is Force?

100

A baseball thrown into the air will continue on its path until which force acts upon it. 

A: Friction

B: Gravity

C: Inertia 

D. Mass

100

Energy can be destroyed

TRUE or FALSE

FALSE

100

Jaxon and Tristen push a cart with the same amount of force.

What Kind of force is this?

BALANCED

200
The force of gravity acts on an object that has this.
What is Mass?
200
A change in the gravitational force acting on an object is its this.
What is Weight?
200

DOUBLE POINTS

STATE THE 1st LAW of MOTION - give an example

An object at rest remains at rest. An object in motion goes at constant speed until an outside force acts upon it.


Back pack on ground - ball on ground - kicked

200

Mr. McNeil puts an invisible screen in front of Evan.

Evan doesn't see him. He runs fulls speed into the screen.

What happens to Evan and why?

Evan will bounce off of the screen due to the equal and opposite force the screen imparts onto evan. 

300

Newton's First Law of Motion is also called

What is "Law of Inertia"

300
The force that pull a falling leaf towards earth is called this.
What is Gravity?
300

What is the 2nd law of motion?


DOUBLE POINTS - GIVE AN EXAMPLE

FORCE=MASS X ACCELERATION


Punting a football

300

I kicked the desk with my foot - what happens and which law does that represent! 

It will hurt because of the 3rd law - The wall will push back against my foot. In an equal and opposite reaction

400

A toy car is released at the top of an INCLINED PLANE. What force is pulling it down?

Gravity (the force of attraction)

400

The tendency of an object to resist a change in its motion is known as this.

What is Inertia?

400
The force that is applied to an object by a person is called this.
What is Applied force?
400

What is the 3rd LAW of Motion?


DOUBLE POINTS - GIVE AN EXAMPLE

For every action there is an equal an opposite reaction! 


2 objects collide -- both will react to the other 

400

Explain a balanced force and give a scenario. 

a set of forces that cancel eachother out. Sitting in a chair: force of gravity pushing you down, chair pushing you up. You don't move. 

500

Moving parts in machinery are coated in oil and grease to reduce this.

What is Friction?

500

A rock setting on the edge of a cliff has what kind of energy?

Potential

500

A ball rolls on a carpet. The ball experience friction as it rolls. How will friction affect the ball´s motion?

A. The ball experiences an unbalanced force and will speed up.

B. The ball experiences an unbalanced force and will slow down
