The distance traveled by an object divided by the time it takes to travel that distance is called
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
In order to determine speed, you must know takes to travel that distance is called

Distance & Time


Zero Km/hr



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



The SI unit for acceleration is

Meter per second2

m/s2


On a velocity time graph a line with a negative slope indicates that the object is
On a velocity-time graph, a line with a negative slope indicates that the object is

Slowing Down




Friction is defined as
Friction is defined as across the line is an example of

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?

  • experiencing friction


Object is in motion when
object is in motion when accelerate. After a period of time, however, the object stops accelerating. What conclusion can be drawn?

  • moves in a point of reference


If the slope of a line on a distance time graph is 1 the speed of the object being plotted is
If the slope of a line on a distance-time graph is 1, the speed of the object being plotted is

increasing


Add water


A car is parked on a hill. In order to keep the car from rolling downhill, how great must the static friction acting on the car be?

friction force must be equal to mg

Mass*gravity


Weight is best described as rolling downhill, how great must the static friction acting on the car be?

Mass*gravity



The greatest gravitational force would occur between the Moon & Earth, or two marbles.

Moon & Earth


The law that states that every object maintains constant velocity unless acted on by an unbalanced force is

First


The law that states that for every action force there is an equal and opposite reaction force is
The law that states that for every action force there is an equal and opposite reaction force is

Third


The law that states that the unbalanced force acting on an object equals the object’s mass times its acceleration is


The SI unit of force, named for the scientist who described the relationship between motion and force, is called the

Newton



Earth pulls on the moon and holds the moon in its orbit. The moon pulls on Earth with an equal and opposite force. This is an example of

  • Newton’s 3rd Law



W = F*d 0


What are the units of work
What are the units of work? does not move. How much work does the boy do on the car?

J or N*m or Kg*m2/s2


  • Which of the following processes requires the most work? does not move. How much work does the boy do on the car?

  • A 10 kg weight rests on a table.

  • A person holds a 1 kg weight still with outstretched arms.

  • A person lifts a 1 kg weight 1 m off the floor.

  • d. A 10 kg ball is rolled across the floor at a constant speed for a distance of 10 m.


280J


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?

Watts
