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
• 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.
