A person exerts a net force on their shopping cart of 40 n. The total mass of the cart and contents it 50 kg. Calculate its acceleration.
acceleration= net force/mass a= 40/50 = 0.8 m/s
I walk at 5 mph for 2 hours. How far do i walk?
distance= speed x time 5x2=10 miles
what is displacement?
it is change in position of the object
if the mass is larger would the acceleration be larger or smaller?
larger
what is motion?
motion is the change in position over time
what is the definition of speed?
speed is measured in meters per second
is a train travels 500 miles in 30 seconds how fast is it going ?
speed= distance/time s= 500 m/ 30 seconds = 16.66 meters
when acceleration is at a right angle to the motion what changes?
the direction of motion changes
what is the formula for distance?
the formula for distance is distance= speed x time
what is the formula for time?
the formula for time is time= distance/speed
what is the formula for speed?
the formula is speed= distance/time
What is a reference point?
the location to which you compare other locations too.
when acceleration is in the opposite direction what happenes
the object slows down
when acceleration is in the same direction as the object moving what increases?
the speed of an object increases
what is velocity?
velocity is speed in a given direction
