Speed and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

True or False: Acceleration only occurs when an object speeds up.

Back

False. Acceleration can also occur when an object slows down or changes direction.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

20 m/s.

Front

What is displacement?

Back

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

Front

If Bill runs 400 meters to Andy's house and back, what is his displacement?

Back

0 meters.

Front

What is the difference between distance and displacement?

Back

Distance is the total path traveled, while displacement is the straight-line distance from start to finish.

Front

What unit is acceleration measured in?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.
