Title: dynamics of newtons laws

1
The Dynamics of Newton's Laws
• By Beckka Prewitt

2
The 5 Forces,
• 1. magnetic
• 2.electric
• 3. nuclear
• 4. gravitational
• 5.weak forces

3
magnetic
• Magnetic forces are produced by moving electric
charges. An example, is when you hold two
positive magnets towards each other, you can feel
the force against the magnets.

4
electric
• electric forces are when something exerts a
force on something else. Example when you push
someone into someone else,(like dominoes) the
energy moves from them to the next person.

5
gravitational
• Gravitational forces are like when you through a
basketball into the hoop. It comes back down.
Gravity pushes the basketball back down to the
ground. So it doesn't float.

6
Gravitational, electric, and, magnetic
• These three forces are able to be monitored on
earth. You can see them. Like dominoes,

7
Weak Interactions and nuclear forces
• These forces CANNOT be monitored on planet
earth. They are so small they cannot be seen.
They appear to be located in the nucleus of
cells.

8
Newton's 1st Law Of Motion
9
Newtons 2nd law of Motion.
• Newton's 2nd law of motion states that, the
force of an object is equal to its mass times its
acceleration. Example if a beach ball rolls down
a hill, it will roll faster as it gets to the
bottom of the hill.
• Fact you cannot know the
• acceleration unless you know
• its mass.

10
Newtons 3rd law of Motion.
• Newtons 3rd law of motion states that, for every
action there is an equal or opposite reaction.
Example if two bowling balls hit together, then
they will go the other way at the same pace.

Newtons 3rd law of Motion.
11
F MxA
• Force Mass x Acceleration.
• You would that the number of the mass and
• multiply by the acceleration, and you would get
• the number of the force.

12
MF/A
• Mass Force / Acceleration
• To get the mass, you have to divide the number of
force
• times the number of acceleration.

13
AF/M
• Acceleration force / mass
• to get the acceleration you have to do force
divided by mass.

14
WMxG
• Weight mass x gravity
• To get the weight. You have to do the mass times
the gravity scale.

15
MW/G
• Mass weight / gravity
• To get the mass, you have to do the weight
divided by the gravity scale.

16
GW/M
• Gravity weight/mass
• To get the gravity number, you have to do the
weight divided by the mass.
