Constant Velocity Flashcard

Front

What does it mean for an object to be moving at a constant velocity?

Back

An object is moving at a constant velocity when it covers equal distances in equal intervals of time in a straight line, without changing speed or direction.

Front

What is the difference between distance and displacement?

Back

Displacement requires direction, while distance does not. Displacement is a vector quantity, whereas distance is a scalar quantity.

Front

What does the slope of a position vs time graph represent?

Back

The slope of a position vs time graph represents the velocity of the object.

Front

What is an example of 1D motion?

Back

A train driving along a straight track is an example of 1D motion.

Front

What does it mean if an object is at rest on a graph?

Back

If an object is at rest on a graph, it means there is no change in position over time.

Front

Define velocity.

Back

Velocity is the rate of change of displacement with respect to time, and it includes both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity with respect to time.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction.

Front

How can you determine if an object is speeding up or slowing down?

Back

An object is speeding up if its velocity is increasing over time, and slowing down if its velocity is decreasing.
