Distance, Displacement, Speed, Velocity and Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the formula to calculate speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

Define displacement.

Back

Displacement is the distance and direction of an object's change in position from a starting point.

Front

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

Back

A flat line on a distance-time graph represents that the object is not moving.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled by an object, while displacement is the shortest straight line from the initial to the final position, including direction.

Front

What is velocity?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = Distance / Time = 100 m / 5 s = 20 m/s.

Front

What is the formula for calculating average velocity?

Back

Average velocity = (final position - initial position) / time.

Front

What does it mean if an object has a negative acceleration?

Back

Negative acceleration indicates that the object is slowing down or decelerating.
