Science Flashcards
Newtons first law of motion
an object in motion stays in motion and an object at rest stays at rest unless acted upon by an outside force
Newtons second law of motion
force=mass x acceleration
newtons third law of motion
for every action (force) in nature there is an equal and opposite reaction
what is speed
the rate at which an object moves
what does speed depend on
distance and the time it takes to travel
what is the formula for speed
distance divided by timew
what is the formula for average speed
total distance/total time
what is velocity
speed with a direction
what is acceleration
the rate at which velocity changes
what is the formula for velocity
distance/time with a north east south or west
what is the formula for acceleration
final velocity-initial velocity divided by time
what is units for acceleration
meter/sec/sec with direction or m/s/s
what does momentum depend on
mass and velocitu
what is the formula for momentum
mass x velocity
what is the symbol for p
lowercase p
