# To investigate the time it takes for a parachute to fall.

Extracts from this document...

Introduction

The Task: To investigate the time it takes for a parachute to fall.

Variables

These variables (factors) will have an effect:

• The length of the string.
• The size of the tissue.
• The size of the hole on the parachute.
• The size and amount selotape used.
• The weight and mass of the plastercine.
• The speed the metre rule is taken away.
• The amount of wind.
• The height the parachute is dropped from.

## The key variable (factor) I am going to change in my investigation is the weight and size of the plastercine at the end of the string.

### Prediction

As I increase the mass of the plastercine at the bottom of the parachute the time taken for parachute to fall will increase.

Middle

Make sure floor is free from wet and slippery substances.

Details of my experiment:

I got a man-sized tissue. Size- (29cmx27.5cm) and folded it into half, and then half again. I got a 1p coin and placed half of it onto the tissue and cut around it. This produced a circle in the middle of the chute.

I then got an arms length of cotton (30cm) string and folded it in half, and half again and tied a knot at the end. This produces 4 strings. Attach each string to each corner of the tissue with 1.5cm in length of selotape. Then stick the tissue together with selotape 1.5 cm in length.

Conclusion- this table of results show that like my prediction the time taken for a parachute to fall decreases as the mass increases was correct.

Terminal velocity is achieved by Newton's 1st law: Balanced forces do not affect the movement of an object: it remains stationary. But in this case Newton also says if the object is already moving it continues to move at the same speed and in the same direction.
