Physics Test 1 Practice

Define distance.

• the relationship between to objects

• the motion of an object between two points in space

• the position of a point in space

• the separation between any two point in space

What does position mean in physics?

• the distance of an object

• the same origin point in space

• a unique location in space

• the distance between two objects in space

How is distance different from position?

• position is always positive, but distance can be negative

• position implies an origin

• distance is relative to speed

• position is below the origin and distance is above it

What is a displacement?

• a change in position

• a change in the origin

• a coordinate system

• two different origin points

What is a vector?

• a type of variable with the same origin point

• a type of variable that includes direction as well as size

• a variable with only positive values and shows direction

• a displacement with no direction and no magnitude

A scalar does not depend on _____.

• position

• distance

• magnitude

• direction

Which of the following is a vector?

• distance

• mass

• displacement

• temperature

What is the difference between distance and displacement?

• both show movement, so they are the same

• one is a vector and the other is a scalar

• distance shows direction, displacement does not

With a vector, what kind of information is carried by the positive and negative signs?

• the direction

• the size

• the math function

• the coordinates

What is the "magnitude" of a vector?

• the units of the vector show magnitude

• the sign of the vector shows magnitude

• the length of the vector shows magnitude

• the direction of the vector shows magnitude
