What describes the first law of newton?
describes what occurs when there is no net force action on an object.
relates accelerated motion to a net applied force.
describes the sy,mmetrical relationship between two interacting bodies.
The force we exert makes things _____.
fly
disapear
move
progress
Can force occur without a force?
true
false
Can you have forces acting on an object without it having motion?
ture
false
what is the difference between the motion of a person that slid on ice versus or a person who slid on a waxed tile flood?
the weight
the momentum
the force
the frictional force
What would happen if the frictional force were to disapear?
an object would move a constant speed along a straight line forever.
the object would move in relation to their mass
the object will be expected to move longer
the object will not move
when a net force acting on an object is zero, the object´s momentum does not change.
first newton´s law
second newton´s law
third newton´s law
Any change in the momentum arises from a change in ______.
aceleration
velocity
speed
momentum
Galileo introduced the term of ____________
intertia
speed
moving
spethors
What is intertia?
the tendency of an object to keep moving in a straight line at a constant speed
to remain stationary when zero net force acts on it.
to increase the velocity due to gravity force
to calculate the forces that act on an object.
what can express what happens when a net force is absent?
the inertia
the newton law
the momentum
the seat belts
What is equilibrium?
the lack of aceleration
the lack of movement
the balance between two weights
Where is the equilibrium applied?
in the construction of buildings
in the balance of the supermarket
in the balance of your lifestyle
how is the second newton law expressed in a number form?
netforce =mass x acceleration
90 N = 50 kg x 78 m/s2
the net force acting on an object is equal to the product of the object´s mass and its aceleration.
aceleration can occur in a
curved path
straight line
zig zag
going up
What would happen if we trow a hammer and a feather at the same time at the moon?
they will have identical acelerations
one will falll first than the other
nothing will happen because they are on the moon
the same as will happen on earth
the second newton law states that _____
the net force acts in the direction in which the object accelerates.
the net force acts in the opposite direction in which the object decreases the acceleration
the momentum will increase as the velocity changes
