Understanding Velocity

Click on the flashcard to see the answer



What is velocity?

Velocity is the speed of an object in a given direction.

How is velocity different from speed?

Velocity includes direction, while speed does not.

What is the formula for velocity?

Velocity = Displacement / Time

What is average velocity?

Average velocity is the total displacement divided by total time.

Can velocity be negative?

Yes, velocity can be negative if the direction is opposite to a chosen positive direction.

What is instantaneous velocity?

Instantaneous velocity is the velocity of an object at a specific moment in time.

What units are used to measure velocity?

Velocity is measured in meters per second (m/s) or kilometers per hour (km/h).

Does velocity change with speed?

Not necessarily; velocity changes only if speed changes or the direction changes.

What is uniform velocity?

Uniform velocity means moving at a constant speed in a straight line.

How do you calculate change in velocity?

Change in velocity = Final velocity - Initial velocity

What is relative velocity?

Relative velocity is the velocity of an object as observed from another moving object.

How can velocity be graphically represented?

Velocity can be represented using a velocity-time graph.

What affects an object's velocity?

An object's velocity is affected by its speed and direction.

What is terminal velocity?

Terminal velocity is the constant speed reached by an object freely falling through a fluid (like air) when the forces of gravity and air resistance are equal.

How does acceleration relate to velocity?

Acceleration is the rate of change of velocity over time.
