Calculating and Graphing Motion

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is usually expressed in km/h.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

If a dog runs 6 km in 30 minutes, what is its average speed in km/h?

Back

12 km/h.

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

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time.

Front

If a truck travels 15 km in 30 minutes going west, what is its average velocity?

Back

30 km/h west.

Front

What does it mean if an object is in motion?

Back

An object is in motion if it changes its position relative to a reference point over time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

How do you calculate acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time.

Front

If a train moves at 561 m per minute, what is its speed in m/s?

Back

9.35 m/s.
