7.7B Describing Motion

Front

What is distance?

Back

Distance is the total length of the path traveled by an object, regardless of direction.

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

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

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

Front

If Jerry walked 5 km to school and then 3 km to the park, what is his total distance?

Back

8 km

Front

If Jerry walked 5 km to school and then 3 km to the park, what is his displacement?

Back

2 km (from home to park directly).

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

If a car travels 60 km in 1 hour, what is its speed?

Back

60 km/hr.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
