Final Exam Study Guide. The distance traveled by an object divided by the time it takes to travel that distance is called. Average Speed. In order to determine speed, you must know. Distance & Time. What is the speed of an object at rest?. Zero Km/hr.
Distance & Time
An airplane is flying at 635 km per hour at an altitude of 35 000 m. It is currently over Kansas and is approximately 16 minutes ahead of its scheduled arrival time. What is its velocity?
No direction = 0
Meter per second2
A force that opposes motion by acting in the opposite direction of motion
A force is continuously applied to an object, causing it to accelerate. After a period of time, however, the object stops accelerating. What conclusion can be drawn?
friction force must be equal to mg
Weight is best described as rolling downhill, how great must the static friction acting on the car be?
The greatest gravitational force would occur between the Moon & Earth, or two marbles.
Moon & Earth
W = F*d 0
J or N*m or Kg*m2/s2
What are the units of power? force of 70 N. If the crate moves a distance of 4.0 m, how much work does the man perform?
height gravity and mass
that energy cannot be created nor destroyed.
Temperature is building and falls a distance of 35 m to the ground. How much work does gravity do on the object from the time it is dropped to the time it hits the ground?
the average kinetic energy of a molecules, feels hot or cold, can be measured
heat increases temperature
Radiation and conduction
The End! body is warmed by
