the Dynamics of newtons laws

• By Brianna Clark

2
Magnetic force

• cause Must observable interactions.
• Magnets pulls stuff together.
• When you have a magnet you can fill the force
  pull the magnet towards the other magnet.

3
Electric forces

• the force when you push something in your hand
  is called electric force.
• This electric forces of repulsion develops as
  electrons in your hand.
• When you are in carpet and you rough your feet
  against the carpet you get electric come on you
  when you touch a door you knob you get shocked.

4
Gravitational forces

• Is an extremely weak force is comparison to the
  other forces
• For example if a ball was in the air it would
  drop because of gravity.
• Gravity pull/keeps ever thing down on earth
• If there were no gravity we would be floating in
  space.

5
Weak interaction and nuclear forces

• They are rarely observable because they exist in
  only inside the nucleus.

6
Newtons first law

• If some thing is in motion it stays at motion
• If some thing is at rest it stays at rest.
• For example an car starts to move then keeps
  moving.
• If a car is in rest it will stay in rest till
  some one move it.

7
Newtons second law

• Four force act on the car that makes it move in a
  straight line at a constant 60km/hr.
• For example if I push some one I used force.

8
Newtons third law

• A body makes force is a second person put force
  on them.
• Like a magnet repels a the other magnet to it.

9
f m x a

• F force
• M mass
• X
• A acceleration
• I push some one in to a one other person

10
Mf/a

• M mass
• F force
• / divide
• A acceleration
• I put lots of force on some thing

11
Af/m

• A acceleration
• F force
• / divide
• m mass
• It take lots of force and mass to move a air plain

12
Wm x g

• W weight
• M mass
• x
• G gravity
• If you were to find the mass and weight of a box
  and if you were to see how long a box that weight
  20p would fall out of gravity.

13
M w/g

• M mass
• W weight
• / divide
• G gravity
• To find the following of a box.

14
Gw/m

• Ggravity
• W weight
• M mass
• find how much of the gravity is pull you down on
  earth.
