Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It includes both the magnitude (speed) and the direction of motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating speed?

Back

The formula for calculating speed is: Speed = Distance / Time.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of matter, while a compound is made of more than one type of matter.

Front

Give an example of an element.

Front

What does a fluctuating line graph represent?

Back

A fluctuating line graph represents a situation where a quantity varies over time, showing increases and decreases.

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it indicates where the object is moving, which is essential for understanding its motion.
