Speed, Velocity, Distance and Displacement

Front

What is speed?

Back

Speed is a scalar quantity that refers to how fast an object is moving, measured as the distance traveled per unit of time.

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, including both speed and direction.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that measures the total path traveled, while displacement is a vector quantity that measures the shortest straight-line distance from the initial to the final position, including direction.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as velocity and force.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction, such as speed and distance.

Front

How do you calculate total distance traveled?

Back

Total distance traveled is the sum of all distances covered, regardless of direction.

Front

How do you calculate displacement?

Back

Displacement is calculated by subtracting the initial position from the final position, taking direction into account.

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 does a steep slope on a distance-time graph indicate?

Back

A steep slope on a distance-time graph indicates that the object is moving at a high speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can involve an increase or decrease in speed or a change in direction.
