Pre AP ICP - Speed and Acceleration - Day 7

Front

What is speed?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If a car accelerates from 0 to 20 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (20 m/s - 0 m/s) / 5 s = 4 m/s².

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

What is the unit of speed in the SI system?

Back

The unit of speed in the SI system is meters per second (m/s).

Front

If a runner covers 100 meters in 10 seconds, what is their speed?

Back

Speed = 100 m / 10 s = 10 m/s.

Front

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

Back

Average Speed = 300 km / 3 h = 100 km/h.

Front

How do you convert km/h to m/s?

Back

To convert km/h to m/s, divide by 3.6.
