Law of Motion
What force is described in the 1st law?
inertia
gravity
friction
speed
friction is...
resistance between 2 surfaces
an object's tendency to resist change
a force of attraction due to mass
how many and what forces include mass as a component?
2, inertia, gravity
1, friction
2, gravity friction
an object with more/less mass will also have:
more/less reaction to friction
more/less gravity
more/less speed
more/less weight
more/less inertia
what is gravity?
a force that opposes motion between 2 surfaces
tendency of an object to resist motion
a force of attraction between 2 objects due to mass
a push/pull
this formula describes the 2nd law.
force=mass times acceleration
energy= mass*speed of light2
y=mxtb
y2-y1/x2-x1
what is a force?
a push/pull
a measure of inertia
what is force expressed in?
newtons
joules
feet
celsius
true/false: air resistance is a form of friction
true
false: it is a form of gravity
false: it is a force
false: it is a form of inertia
balanced forces produce motion
true
false
unbalanced forces produce motion
true
false
what units are expressed in a speed graph?
distance/time
distance/direction
time/velocity
acceleration/gravity
what graph uses velocity/time?
acceleration
speed
direction
momentum
what is a reference point?
A place or object used for comparison to determine if an object is in motion
An object's change in position relative to a reference point.
Distance and direction of an object's change in position from the starting point.
how to calculate speed?
distance/time
speed*time
speed/time
how to calculate distance?
speed*time
distance/time
speed/time
what is velocity?
speed in a given direction
distance/time
change in velocity
what cues acceleration?
speeding up/slowing down
constant speed
change in direction
no movement
what is deceleration?
slowing down
negative acceleration
speeding up
constant speed
balanced force
two or more forces that are not equal and opposite of one another; can cause change in motion
a push or a pull exerted on an object in order to change the motion of the object; force has size and direction
two forces acting in opposite directions on an object, and equal in size
if a person pushing a box to the right is using 600 newtons of force, and 5 other people are pushing it to the right with 100 newtons of force each, what direction does the box move and what is the net force?
it moves right 100
it moves left 100
stays still 0
explodes 0
what is net force?
total of each side of the unbalanced force
how much a force weighs
how many newtons a force has
how many newtons an object has
A car is driving at 35 mph. There is a car crash in front of the driving car. The driver and passengers are flew forward but stopped by the seatbelts. What Law of Motion is in effect?
1ST law
2nd law
3rd law
there is no law in effect
all laws are in effect
A F150 and a Mazda have a car collision. According to Newton's 2nd law, which object has more mass?
the truck
the mazda
the van watching from the side
they have the same mass
Air rushes out of a balloon. What is the opposite reaction, according to the 3rd law?
the balloon rises
the balloon does not move
the balloon explodes
the balloon descends
the balloon deflates
Compare an empty shopping cart to a full one. Which one requires more force to push?
the full one
the empty one
they require the same amount of force because each one has the same mass
they require the same amount of force because they have the same amounts of acceleration
A muscleman is lifting weights up. The muscleman is pushing the weights with 7000 newtons of force. Gravity and air resistance have varying amounts of force, between 3000-5000 newtons of force each. Which direction do the weights move?
the weights move up
the weights move down
the weights repeat a cycle of up and down movement
the weights do not move.
A person is about to dive into a pool. The diving board pushes down as the person gets into position. The reaction is the board moving up. What law of motion is this?
3rd law
all laws
2nd law
1st law
none of the laws
