Title: The Dynamics of Newtons Laws

1
The Dynamics of Newtons Laws.
• By Delaney Bromagen

2
Magnetic Force
• Magnetic forces are very large in comparison to
gravitational forces. They are produced by moving
electric charges. Electric and magnetic forces
are closely related.

3
Electric Force
• The force that appears when you push or pull
something. Repulsion develops as the electrons of
the hand are brought close to the electrons of an
object.

4
Gravitational Force
• Is an extremely weak force compared to the other
forces. If two tennis balls are held one meter
apart, the gravitational force between them is
only .00000000001.

5
Weak Interaction and Nuclear Force
• Nuclear forces are much stronger then any other
forces. It holds the nucleus of an atom together.
A second force also is inside the nucleus. It is
the weak interaction because some of the atoms
are known to break apart.

6
Newtons First Law and Real Life Example
• Newtons first law of motion is An object at
rest will stay in rest, unless acted upon by an
outside force. An example could be if you roll a
tennis ball on the floor it will keep going until
someone or something stops it.

7
Newtons Second Law and Example
• An unbalanced force causes acceleration. For
example, two cars, one car at rest while the
other collides into it fast when driving in a
straight line. The car at rest is acted upon by
the moving car.

8
Newtons Third Law and Real Life Example.
• This is the law of action and reaction. States
that every force is accompanied by an equal and
opposite force.
• An example could be a charged body repels another
body.

9
FMA
• Force equals mass times acceleration
• An example could be the acceleration of a 2kg
brick thrown with a force of 4 newtons.

10
MF/A
• Motion- Force and acceleration.
• An example could be if you have an engine that
can provide a force of 5.6 newtons, and place the
engine on a cart so it accelerates at 3.5/s/s.

11
AF/M
• Acceleration force divided by mass
• Example- if the acceleration of a hammer is 6,
then the force could be 36 and the mass would be
6.

12
WMG
• Weight equals mass times gravity.
• An example could be if your weight is 48 then
