Relationship Between Force & Motion 7.7 ABCD

Front

What is speed?

Back

Speed is defined as distance traveled divided by the time taken.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

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).

Front

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

Back

60 km/h

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time.

Front

What does a steeper incline do to the speed of an object?

Back

A steeper incline generally increases the speed of an object due to greater gravitational force acting on it.

Front

What is displacement?

Back

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

Front

If a truck moves 50 km in 1 hour, what is its average speed?

Back

50 km/h

Front

What is the average velocity of a car that travels 100 km east and then 50 km west?

Back

25 km east.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit time.
