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
