Flashcards in Resultant Forces Deck (9):
1

What is the Resultant Force?

The overall force on a point or object

2

How many forces are acting on an object is most real situations?

2

3

What does the overall effect of these forces have on an object?

Motion - accelerate, decelerate or a steady speed

4

If you have a number of forces acting at a single point/object, you can replace them with a [ ] force (so long as the single force has the same effect on the [ ] as the [ ] forces)

single
motion
original

5

If the forces all act on a straight line (act in the same or opposite direction), how is the overall effect calculated?

By adding / subtracting them

6

Which direction does the force of gravity act in?

Downwards

7

What is the reaction force?

It's the force from the surface pushing up on an object

8

Gravitational force = Reaction force then the resultant force = [ ] and the object is [ ]

0 N
Stationary

9

Resultant force means a change in...
