Motion Test Review

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

Define displacement in the context of motion.

Back

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

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity representing the total path length traveled, while displacement is a vector quantity that considers the shortest path and direction.

Front

How do you calculate speed?

Back

Speed = Distance / Time

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What does a positive acceleration indicate?

Back

Positive acceleration indicates that an object is speeding up.

Front

If a car travels at a speed of 60 mi/hr for 2 hours, how far does it travel?

Back

120 miles

Front

If a person walks 100 m east and then 100 m west, what is their displacement?

Back

0 m (displacement is zero because the starting and ending points are the same).

Front

What is the average speed of a car that travels 300 km in 3 hours?

Back

100 km/hr
