Physics - Speed and Acceleration

Front

Basic SI unit of length or distance is:

Back

Meter

Front

At what speed would a car have to move in order to travel 20 kilometers in 2 hours?

Back

10 km/hr

Front

What two things must you know to determine speed?

Back

Time and distance

Front

Distance over time (m/s) is known as:

Back

Speed

Front

Speed = _______________

Back

Distance / time

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).

Front

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

Back

20 m/s

Front

What is the unit of acceleration in the SI system?

Back

Meters per second squared (m/s²)

Front

Define constant speed.

Back

Constant speed means moving at a fixed distance per unit of time.
