Speed, Velocity, Acceleration, Graph - Flashcard #2

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/h) or meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time. It can be positive (speeding up) or negative (slowing down).

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is not moving (at rest).

Front

What does a straight diagonal line on a distance-time graph represent?

Back

A straight diagonal line represents constant speed.

Front

What does a curved line on a distance-time graph indicate?

Back

A curved line indicates changing speed, which can represent acceleration or deceleration.

Front

How do you calculate distance using speed and time?

Back

Distance = Speed × Time.

Front

If a runner travels at a speed of 10 km/h for 3 hours, how far do they travel?

Back

30 km.

Front

What does a negative slope on a distance-time graph represent?

Back

A negative slope indicates that the object is returning to its original position.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the starting point to the endpoint.
