What is the difference between a vector and a scalar?

Front

Scalars only have magnitude, vectors also have direction

Back

In a "v vs. t" diagram, what corresponds to the acceleration of the object?

Front

Slope

Back

What is the difference between clock reading and time interval? What is their standard unit?

Front

Clock readings is a point in time, time interval is a length of time

Back

In an "x vs. t" diagram, what indicates the direction of motion of the object?

Front

Whether the graph goes upwards or downwards

Back

In a track diagram, what indicates the speed of an object?

Front

Distance between two successive tracks

Back

What is position? What is its symbol?

Front

Location with respect to an origin; x

Back

In an "x vs. t" diagram, what indicates the speed of an object?

Front

Slope

Back

In a "v vs. t" diagram, what corresponds to the displacement of the object?

Front

Area under the curve

Back

In a "v vs. t" diagram, what is an easy way to visualize the motion of the object?

Front

Draw arrow from the H-axis to the graph

Back

What is the difference between distance and displacement?

Front

Distance- total distance depends on path taken; displacement- only depends on initial and final endpoints, has direction

Back

What does the sign of acceleration indicate?

Front

Direction of a-arrow (left or right, up or down)

Back

What does the magnitude of the acceleration indicate?

Front

How quickly velocity is changing

Back

What is the rule to determine the direction of acceleration given velocity vectors?

Front

It is in the same direction as the net pull

Back

What is magnitude?

Front

Size of a quantity

Back

What is displacement? What is its symbol? What is its standard unit?

Front

Shortest distance between 2 points with direction; delta x; m

Back

What is the difference between speed and velocity?

Front

Velocity has direction

Back
