Mystery
100
This happens to an object when it has positive acceleration.
What is speeding up?
100
This is happening to an object when it has negative acceleration.
What is slowing down?
100
A baseball thrown into the air will continue on its path until which force(s) acts upon it.
gravity and air resistance
100
The action of moving sediment to a new location.
What is Erosion?

Who discovered the Laws of Motion?
Who is Sir Issac Newton?
200
A push or a pull exerted on an object is called this.
What is Force?
200
In absence of acceleration, a moving object has a constant this.
What is Speed?
200
Moving parts in machinery are coated in oil and grease to reduce this.
What is Friction?
200
When sediment is left in a new location it is called...
What is Deposition?

Gravitational force affecting Mass is...
What is Weight?

DAILY DOUBLE!!
A 20 kg ball and a 50 Kg ball rest at the top of a ramp. Which has greater force?
They are both at rest so it is the same
300
Distance / Time = ?
What is Speed?
300
A parachute works to do this so that you don't crash and get hurt.
Increase air resistance
300
When the same scientist repeats their own experiment multiple times to check for consistency and reduce errors.
What is Scientific Repetition?

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.
400
The tendency of an object to resist a change in its motion is known as this.
What is Inertia?
400
When an object has 0 Net Force it is...
What is Balanced?
400
What is the force that is pushing up on a book that is sitting on a desk?
What is the NORMAL FORCE?
400
When other scientists perform the same experiment independently to see if they get similar results.
What is Scientific Replication?
400
This is the what gravity acts on to give an object its weight
What is Mass?
500
Describe the movement at each letter.
A - The object/person is moving at a slow constant speed.
B - The object/person is not moving.
C - The object/person is moving at a fast constant speed.
D - The object/person is not moving.
500
Which direction is the object moving and what is its Net Force?
It is moving 250N to the right. (Red Arrow)
500
The larger the mass, the bigger this force is

What is the 3rd LAW of Motion?
For every action there is an equal an opposite reaction!
2 objects collide -- both will react to the other
