Slowing us Down
A bike slowing down on grass is an example of this force.
What is friction?
This force is what causes an object to weigh a certain amount on Earth.
What is gravity?
When you give a speed and direction, you are measuring this.
What is Velocity
An object in motion will stay in motion until this is acted upon it.
What is force?
This is the equation to find the force of an object.
What is f = ma
force = mass x acceleration
Oiling a squeaky hinge on a door increases or decreases the friction of the hinge?
What is decrease?
Object A weighs 5kg and has a velocity of 10mph to the left. Object B weighs 10kg and has a velocity of 10mph right. The objects do this when they collide.
What is stop
Students cried this morning when they found out their favorite teacher was going to be absent. Name that teacher.
Who is Mr. Mac
This scientist created the 3 laws of motion that we use to understand the motion of objects.
Who is Sir Isaac Newton?
These are the two types of forces.
What is push and pull?
This student needs his friends to walk him home so he makes it safely.
Who is Willie?
This characteristic causes an object to have more gravitational force.
What is mass
Mass times this characteristic of an object equals force.
What is acceleration?
This student thinks F=ma is from Spanish class?
Who is Josue?
An object at rest tends to stay at...
What is rest?
Using snow tires on a snowy road does this to friction.
What is increase?
This student needs to be Forced out of bed to make it to school?
Who is Kerry?
The measure of something changing speeds, changing directions, stopping or starting.
What is acceleration?
This law is also known as the law of acceleration
What is Newton's Second Law.
This superhero would lose to all other superheroes in a fight.
Who is Wolverine?
Friction causes an object to do this.
What is slow down?
This object is kept close to earth by gravity
What is the moon?
This force decreases the speed of an object by pulling or pushing in the opposite direction of the object.
What is friction?
Newton's 3rd law of motion says.
What is for every action there is an equal and opposite reaction?
The ability of an object to resist change in its state of motion.
What is inertia?
