Speed Velocity and Acceleration

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

Define acceleration.

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What does a horizontal line on a distance-time graph represent?

Back

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

Front

What is the unit of acceleration in the SI system?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

How can you determine if an object is accelerating?

Back

An object is accelerating if its velocity is changing, which can be indicated by a change in speed or direction.

Front

What does a steep slope on a speed-time graph indicate?

Back

A steep slope indicates a high rate of acceleration or deceleration.

Front

What is uniform motion?

Back

Uniform motion occurs when an object travels equal distances in equal intervals of time.

Front

What is the relationship between distance, speed, and time?

Back

Distance is equal to speed multiplied by time (Distance = Speed x Time).

Front

What is the significance of the area under a speed-time graph?

Back

The area under a speed-time graph represents the total distance traveled by the object.
