Newton's Laws Flashcards
A push or pull on an object
Force
Two forces acting opposite directions on an object, equal in size
balanced force
the combination of all forces acting on an object
net force
This causes movement or acceleration
unbalanced force
The force that causes a moving object to slow down when it touches another object
Friction
A measurement of how quickly something is moving
speed
Speed plus a specific direction
Velocity
The rate at which an object changes its speed or direction. It can be speeding up, slowing down or changing direction.
acceleration
a force that is applied to an object by a person or another object
applied force
An English physicist and mathematician that formulated the three basic laws of motion
Sir Isaac Newton
a tendency to do nothing or remain unchanged
inertia
An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force
Newton’s First Law
F = M x a
Newton’s Second Law
The acceleration of an object is dependent upon two things, the net force (F) and
the mass of the object
The greater the amount of mass an object has the greater the amount of __________needed to accelerate it
force
For every action there is an equal and opposite reaction
Newton’s Third Law
Unbalanced forces create volcanoes, mountains and rift valleys when tectonic plates are under tension. Which law is this an example of?
Newton’s Third Law
A book sitting on a shelf. Which Law is this an example of?
Newton’s First Law
A rocket taking off
Newton’s Third Law
A satellite orbiting the Earth
Newton’s First Law
A 13 year old boy kicking a soccer ball will kick it farther than a 2 year old boy because they are able to exert more force
Newton’s Second Law
A baseball being hit with a baseball bat
Newton’s Third Law
Measured in Newtons
Force
Measured in kilograms
mass
measured in m/s/s
Acceleration
When you paddle a canoe your oar goes backwards but the canoe moves forward
Newton’s Third Law
