Moving parts in machinery are coated in oil and grease to reduce this.
What is Friction?
100

A free body diagram showing a diver in free fall.


What is balanced forces of drag (air resistance) and gravity.

100

The action / reaction pair of an ice skater on the ice being lifted by her partner.

Mrs. Hosler will verify correct answer

100

Daily Double: Your new motorcycle weighs 2450 N.  This is the mass in kilograms.

What is 2500 N?

100
This force opposes the movement of an object when it travels through the air or water.
What is Drag force?
200
This is happening to an object when it has negative acceleration.
What is slowing down?
200
DAILY DOUBLE:  A grocery sack can withstand a maximum of 230 N before it rips.  Will a bag holding 15 kg of groceries that is lifted from the checkout counter at an acceleration of 7.0 m/s2 hold?

What is 250 N - It does not hold.

Daily Double: Draw a free body diagram of a book being pushed across the table with a  cell phone sitting on top. (object is the book)

Mrs. Hosler will check

200
A change in the gravitational force acting on an object is its this.
What is Weight?
200
The magnitude of this force is the same as an object's weight.
What is Gravity?
300
In absence of acceleration, a moving object has a constant this.
What is Speed?
300
When the only force acting on an object is gravity, the object is in this.
What is Freefall?
300

This will not change, no matter where you may find yourself.

What is Mass?

300

For every action, there is an equal and opposite reaction

What is Newton's Third Law?

300
Daily Double: A student stands on a bathroom scale in an elevator at rest on the 64th floor of a building.  The scale reads 836 N.  As the elevator moves up, the scale reads 936 N.  What is the acceleration of the elevator?

What is 1.17 m/s2?

400
The force exerted by a surface that opposes an object's effort to move across it is this.
What is Friction force?
400
The tendency of an object to resist a change in its motion is known as this.
What is Inertia?
400

An object at rest will remain at rest while an object in motion will remain at a constant velocity unless enacted upon by a net unbalanced force.

What is Newton's First Law?

400
The force that is applied to an object by a person is called this.
What is Applied force?
400
This is the force transmitted through a string, rope or cable when it is pulled from one end.
What is Tension force?
500
This happens to an object when it has positive acceleration.
What is speeding up?
500
A push or a pull exerted on an object is called this.
What is Force?
500
This is the measure of the amount of an object's matter.
What is Mass?
500
This force is exerted upon an object that is in contact with another object.
What is Normal force?
