Concepts&Definitions

100

When you are adding vectors, the sum of them is called the ____ vector 

Resultant 

200

Mass acts as a measure of_________

Inertia 

300

Define vector and give an example 

Vector is a quantity with a magnitude and direction 

Many acceptable answers 

- velocity 

-force

-weight 

- acceleration 

400

List 3 types of forces 

Gravitational 

Normal/Contact 

Buoyancy 

Push/Pull

Friction 

(any of these are acceptable)  

500

Define force 

A push or a pull acting on an object as a result of an interaction with another object

Newtons laws

100

An object in motion.....

Stays in motion 

200

If earth applies a force Of 66 million Newtons to the moon and the radius Of the earth is 3,963 miles, what force will the moon apply back to earth.

66 million Newtons 

300

What will an object moving 6 m/s be doing if all forces were balanced 

the object would continue to move at a CONSTANT speed of 6m/s 

400

What is the formula For Newton‘s second law of motion 

Fnet=ma

500

A rocket is sent to space with an initial velocity of 650,000 m/s. What will happen to the rocket once it reaches space and the engine is turned off.

It will continue moving because an object in motion stays in motion unless acted upon by another force.

Relationship

100

If mass of an object is tripled, what happens to the net force 

Net force is tripled

200

If force of friction is greater than applied force what will the object accelerate or decelerate 

The object will decelerate 

300

If mass is doubled and acceleration is doubled, what will happen to net force 

The net force will increase by a factor of 4

400

If someone’s weight is less than their mass, (gravity is 0) they are probably (a location) 

In space because there is no gravity in space 

F(g), which is weight, would be mass x 0

500

If someone Standing on the ground’s mass is cut in half and the acceleration of gravity is Somehow increased by A factor of 6, what will happen to the normal force the ground applies to the person 

The normal force the ground applies back will increase by a factor of 3
