Title: newtons three laws

1
The dynamics of Newton's law
• ByG.Arnett

2
Magnetic Force
• The force between to magnets is magnetic force.
• You can feel magnetic force when you put a
positive side of a magnet to another part of the
magnet then you can feel the force that is
pushing.

3
Electric Force
• A electric force is a force from electricity.
• A example of electric force is when something has
electrical energy and it give a force to another
object.

4
Gravitational force.
• When the only force on a object is gravity it
will fall. This is also called free falling.
• A example is when a apple is falling from a tree
is a gravitational force.

5
Weak interactions and nuclear force
• Weak interactions and nuclear forces are hard to
observe because they are formed in the nucleus.

6
Newton's first law.
• An object at rest stays at rest and an object in
motion stays in motion with the same speed and in
the same direction unless acted upon by an
unbalanced outside force.
• A hockey puck will slide till something stops it
or it runs out of power.

7
Newton's second law
• The acceleration of an object as produced by a
net force is directly proportional to the
magnitude of the net force, in the same direction
as the net force, and inversely proportional to
the mass of the object.

8
Newton's third law
• For every action, there is an equal and opposite
reaction.
• If you shoot a basketball the equal reaction
would be it going into the basket the oppisit
reaction would be it not going in.

9
FMA
• Force massacceleration
• Example- when pushing a car to find out how much
force there is you have to multiply the mass
times the acceleretion.

10
MF/A
• MASS FORCE / ACCELERATION
• A 300g cart reaches a speed of 50m/s in 20
seconds from a standing start.

11
AF/M
• ACCELERATIONFORCE/MASS

12
WMG
• WEIGHT MASS GRAVITY

13
MW/G
• MASS WEIGHT/ GRAVITY

14
GW/M
• GRAVITY WEIGHT/ MASS
