Title: The Dynamics of Newtons Laws

1
The Dynamics of Newtons LawsDynamics is the
study of forces which cause motion
• By Callie Arnold and Amy Ginter

2
Magnetic Force
• A force that exists between two electrically
charged moving particles.
• They are very large compared to gravitational
forces.
• Electric and magnetic forces are very closely
related.

3
Electric Force
• Very large.
• Produces magnetic forces by moving electric
charges.
• Results from electron repulsion of two objects.

4
Gravitational Force
• The weakest of all the forces.
• It is very small compared to magnetic and
electric forces.

5
Weak Interaction and Nuclear Force
• The strongest of all the forces.
• Some power plants use nuclear power to provide
electricity to cities today.
• Holds the nucleus of an atom together.

6
Newtons First Law
• A body continues in its state of rest, or of
uniform motion in a straight line, unless it is
acted upon by a net external force.
• If you roll a tennis ball on the floor it will
keep going unless its acted on by an outside
force.

7
Newtons Second Law
• When an unbalanced force acts on a body, the body
will be accelerated.
• Two cars, one at rest and one driving in a
straight line, and they collide. The car at rest
is acted upon by the moving car.

8
Newtons Third Law
• Every force is accompanied by an equal and
opposite force.
• A charged body repels another body.

9
FMA
• Force equals mass times acceleration
• If the force of your hammer on a nail is 36, then
your mass and acceleration would be 6.

10
MF/A
• Mass equals force times acceleration
• If your mass of the hammer is 8, then your force
could be 32 and your acceleration could be 4.

11
AF/M
• Acceleration equals force divided by mass
• If the acceleration of your hammer is 12, then

12
WMG
• Weight equals mass times gravity
• If your weight is 48, then your mass could be 12,
and your gravity could be 4.

13
MW/G
• Mass equals weight divided by gravity
• If your mass is 11, then your weight could be 22
and your gravity would be 2.

14
GW/M
• Gravity equals weight divided by mass
• A car could have the gravity of 100, weight of
200, and mass of 2.
