Motion, Speed, and Velocity

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

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

If a car travels 150 miles in 3 hours, what is its speed?

Back

50 miles/hour

Front

What is the unit of measurement for speed in the metric system?

Back

Meters per second (m/s) or kilometers per hour (km/h)

Front

Define motion in the context of physics.

Back

Motion is the process of changing position relative to a reference point.

Front

What is the average speed of an object?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

How do you calculate velocity?

Back

Velocity = Displacement / Time, where displacement is the change in position.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity because it differentiates it from speed, making velocity a vector quantity.

Front

If a runner completes a 400-meter lap in 50 seconds, what is their average speed?

Back

8 meters/second
