REQUIRED PRACTICAL- Investigating force and acceleration

Question 1

WHAT IS THE AIM OF THE EXPERIMENT?

Answer 1

to determine relationship between force mass and acceleration

Question 2

WHAT IS THE INDEPENDENT VARIABLE

Answer 2

applied force

Question 3

WHAT IS THE DEPENDENT VARIABLE?

Answer 3

acceleration of trolley

Question 4

WHAT IS THE CONTROL VARIABLE?

Answer 4

the trolley

Question 5

EXPLAIN WHAT EQUIPMENT YOU WILL NEED?

Answer 5

-Motion senser
-Interface
-Computer
-Trolley with card
- Newton meter
- Masses

Question 6

EXPLAIN HOW TO CARRY OUT EXPERIMENT WITH FORCE?

Answer 6

-Set up motion senser equipment measuring out a set distance from the front of the senser to the trolley with a meter ruler (1m)
-Starting by pulling your newton meter to 1N TROLLEYS MASS SHOULD NEVER CHANGE
-Keep doing this all the way to 10n and allow motion sensor to draw velocity time graph

Question 7

WHAT SHOULD THE RESULTS OF THE VELOCITY TIME GRAPH FOR FORCE SHOW.

Answer 7

acceleration increasing meaning Force is directly proportional to acceleration as when Force increases so does acceleration

Question 8

HOW WOULD YOU ALTER THIS PRACTICAL FOR MASS?

Answer 8

keep constant force on trolley 5N but use masses and keep adding to trolley

Question 9

WHAT SHOULD VELOCITY TIME GRAPH FOR MASS SHOW?

Answer 9

that mass is inversely proportional to acceleration and if mass increases acceleration decreases
