Title: the Dynamics of newton’s laws


1
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.
