force
what is force
a push or pull
a speed that uses direction
what is acceleration?
the amount a object speeds UP.
equation for force
f=MA
a football lays on the ground motionless, balanced or unbalanced
balanced
what is the unit for force
Newtons (N)
(velocity or speed) A car moves 8 newtons a second north
velocity
what happens to acceleration if it stops?
the acceleration goes down
how do you net force?
subtract the numbers if one goes against another, add if they go the same direction.
a box is pushed by someone on the right, the person on the left is also pushing, it doesn't move, balanced or unbalanced?
balanced
what is newtons second law?
f=MA
what is the difference between velocity and speed?
velocity is direction based and speed isnt
what happens if a car is gradually speeding up
it grows in acceleration
someone pushes a box 4N to the right, and someone pushes the box 4N to the left, what is the net force.
zero newtons
a person pushes a table about 8 newtons, and a ghost pushes on the other side at 9 newtons, balanced or unbalanced
unbalanced.
what law is action reaction?
3rd
(velocity or speed) a recycling truck moves at a consistent speed of 3 k/m
speed
a car is going 80 meters a second, it speeds up, this is _____
a box is pushed 200N on the right, and on the left a vehicle pushes the box at a speed of 40 km/h and weighs 800 kg. what is the net force, and is this balanced?
31,800N, not balanced.
a person pushes a box 600 newtons, on the other side, a person pushes a box 504 newtons, balanced or unbalanced
unbalanced
what are the non contact forces
magnetism, electricity, gravity
speed is a non direction based, velocity is based off direction, if your driving at 30 meters a minute consistently, and you turn, is this velocity or speed
velocity
true or false, acceleration is a part of newtons second law being in the equation for force..?
true
a F1 race car moves 200 kilometers a hour on average, weighing 800 kg, what is the average force is produces?
160,000 newtons.
a person that has a mass of 16 kg pushes a box at a acceleration of 8 m/s2, on the other side, a person with a mass of 34 kg pushes back with a acceleration of 4 m/s2, balanced or unbalanced
unbalanced
