Resultant Forces Flashcards
1
Q
What does ‘No Resultant Force’ mean?
A
- No change in velocity
2
Q
Define ‘Resultant Force’
A
- The overall force acting on a body
- Acceleration
3
Q
Describe what will happen if the resultant force acting on a body is not zero
A
- It will accelerate in the direction of the resultant force
4
Q
What will an ‘unbalanced force’ always produce?
A
- Acceleration
- Five different forms
5
Q
What are the five different forms of acceleration?
A
- Starting
- Stopping
- Speeding up
- Slowing Down
- Changing Direction
6
Q
Define ‘Force’
A
- A vector quality which has magnitude and direction
7
Q
Describe the pattern found
A
- Bigger the mass of an object, smaller the acceleration
8
Q
What has to be done to get a big mass to accelerate as fast as a small object?
A
- A larger resultant force
9
Q
What is the equation to work out the resultant force?
A
- Force = Mass x Acceleration
