Unit#02: Linear Motion (NR) Review

Front

What is the difference between velocity and speed?

Back

Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only measures how fast an object is moving.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What is the correct unit for measuring speed in the metric system?

Back

The correct unit for speed in the metric system is meters per second (m/s).

Front

What does acceleration measure?

Back

Acceleration measures the rate of change of velocity of an object over time.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final velocity (v_f) - Initial velocity (v_i)) / Time (t).

Front

What is the unit of acceleration in the metric system?

Back

The unit of acceleration in the metric system is meters per second squared (m/s²).

Front

What does a speed-time graph represent?

Back

A speed-time graph shows how speed changes over time, with speed on the vertical axis and time on the horizontal axis.

Front

What does a horizontal line on a speed-time graph indicate?

Back

A horizontal line on a speed-time graph indicates that the object is moving at a constant speed.

Front

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

Back

A steep slope on a distance-time graph indicates a high speed.
