Forces Flashcards
1
Q
In a diagram, what do the arrows show?
A
- The size and the direction of forces
2
Q
What does a stationary force have?
A
- All forces in balance
3
Q
Describe gravity
A
- Gravity is also called ‘weight’
- This force acts downwards
4
Q
Describe what gravity does
A
- It causes a reaction force from the surface pushing the object back up.
- This is the only way it can be in balance
5
Q
What would happen to an object without there being a reaction force?
A
- The object would accelerate downwards due to the pull of gravity
6
Q
What are the similarities between ‘Steady Horizontal Velocity’ and ‘Steady Vertical Velocity’?
A
- They both have all forces in balance
7
Q
Describe the features which ‘Horizontal Acceleration’ has
A
- Unbalanced forces
- Acceleration comes from an overall unbalance force where the length of one arrow is longer than the arrow in the opposite direction
8
Q
What is the pattern for ‘Bigger the unbalanced force’…
A
- Greater the acceleration
