Title: Newton's laws

1
The dynamics of Newton's laws
2
Magnetic Force
• Magnetic forces are produced by moving electric
charges.

3
Electric Force
• The force that appears when you push on
something with your hands is electric force. This
electric force of repulsion develops as the
electrons of the hand are brought close to the
electrons of an object.

4
Gravitational Force
• Gravitational force is an extremely weak force
in comparison to the other forces.

5
Weak Interaction and Nuclear Forces
• Nuclear forces are much stronger than other
forces. The nuclear force holds the nucleus of an
atom together in spite of the strong electric
force of repulsion between its protons.

6
Newton's first law
• His first law of motion states, 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.

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

8
Newton's third law
• The third law says that for every action there
is an equal and opposite reaction. Forces are
found in pairs.

9
FMxA
• The more force the more acceleration. F force,
A acceleration, M mass.

10
M F/A
• m mass, f force, a acceleration

11
AF/M
• A acceleration, F Force, M mass. This means
acceleration equals force divided by mass.

12
W MxG
• W means weight, M means mass and G means
gravity. This means weight equals mass multiplied
by gravity.

13
M W/G
• M means mass, W means weight, and G means
gravity. This means that mass equals weight
divided by gravity.
