Flashcard#5

Front

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

Back

Time = Distance / Speed

Front

If a person walks 4 km at a speed of 2 km/hr, how long did they walk?

Back

2 hours

Front

What is the average speed of a car that travels 715 km in 6.5 hours?

Back

110 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 a reference point in motion?

Back

A reference point is a place or object used for comparison to determine if another object is in motion.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

If a car accelerates from 0 km/s to 124 km/s in 3.7 seconds, what is the acceleration?

Back

33.5 m/s²

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s) or kilometers per hour (km/h)

Front

What does it mean if an object is in motion?

Back

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

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time
