Force a push or pull
Describe force: By its strength and by the direction in which it acts
SI unit used to measure strength newton
How can direction and strength of force be represented? By an arrow (head tells direction) (length indicates strength)
Net force the overall force on an object when all the individual forces acting on it are added together
What does net force determine? whether an object moves and which direction it moves
How to find the net force when two forces act in the same direction? add the strengths of the individual forces together
When two forces act in the same direction what does it do to the net force? Produces a greater force
How do you find the net force when two forces act in opposite directions? subtract the strengths
When two forces act in opposite directions what does it do to the net force? produces a net force in the direction of the larger force
If the net force is zero will the objects motion change no because the forces acting on the object are balanced
Unbalanced force forces that produce a non zero net force(which changes an objects motion)
Balanced force equal forces acting on an object in opposite directions
How do balanced forces acting on each other affect it's motion? balanced forces cancel and do not change the objects motion
