Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position. It includes both speed and direction.

Front

What are the two components of velocity?

Back

Speed and direction.

Front

What is an independent variable in an experiment?

Back

An independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

In Zach's experiment, what is the independent variable?

Back

Time on social media.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

If you travel 25 meters in 10 seconds, what is your speed?

Back

2.5 m/s.

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that shows a consistent distance over time.

Front

What does acceleration mean?

Back

Acceleration is the rate of change of velocity of an object. It can be an increase or decrease in speed.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

If an object travels at a speed of 4 m/s for 5 seconds, how far does it travel?

Back

20 meters.
