Front

What is displacement?

Back

The change in position of an object (difference between starting point and ending point)

Front

What is the difference between displacement and distance?

Back

Displacement is the shortest path between two points, while distance is the total path traveled.

Front

How do you calculate resultant displacement?

Back

Resultant displacement is calculated by vector addition of individual displacements.

Front

What is the formula for calculating the components of a vector?

Back

Rx = R * cos(θ), Ry = R * sin(θ)

Front

What does a constant rate of motion look like on a graph?

Back

A straight line with a constant slope indicates constant speed.

Front

What is the significance of the slope in a distance-time graph?

Back

The slope represents the speed of the object.

Front

During which interval is an object at rest?

Back

An object is at rest when its position does not change over time.

Front

What is the formula for average speed?

Back

Average speed = Total distance / Total time.

Front

How do you determine the direction of a resultant vector?

Back

The direction of the resultant vector is determined by the angle it makes with a reference direction.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.
