tendency to resist change in motion





10.

measure of how far and object has moved





11.

speed and direction of motion





12.

compare and contrast: distance and displacement


both are links; displacement is direction and distance; distance is how far you have moved



15.

compare and contrast: speed and velocity


both meters per second: speed is distance and velocity is speed and direction

how are force and motion related?


both take unbalanced force to cause motion



18.

what property of matter is inertia related to?





19.

a car travels west for 240 kilometers in 4 hours. What is the car's velocity?

22.

the amount of matter in an object





23.

the net force acting on an object is zero





24.

the speed of an object and the direction of its motion





25.

the sum of all the forces acting on an object





26.

rate of change of the velocity of an object





27.

a measure of how far an object has moved





28.

the rate of change in position at a given point in time





29.

the distance and direction an object moves from its starting point





30.

the total distance an object travels divided by the time of travel





31.

the rate of change of an object's position





32.

unequal forces pushing in opposite direction





33.






34.

an object that is neither speeding up or slowing down travels at a________.





35.

a graph with distance on a vertical axis and time on a horizontal axis





36.

when an object is accelerating, its speed is_______.





37.



an object at rest will remain at rest until an unbalanced force acts on it



38.

if the net force acting on a body is zero, will the velocity be zero?


no the velocity is constant, the object will not change its motion



39.

will all forces cause an object to accelerate?


no only an unbalenced force

43.

the equation s=d/t is used to calculate the_____ of an object





44.

in terms of positive, negative, and zero exceleration, how would you describe the motion of a student moving in a cafeteria lunch line


stand still zero
forward positive
backwards negative



45.

explain why the second hands of a clock cannot travels at constant velocities


they are changing direction



46.

can the velocity of a car change when it's acceleration is constant? explain why or why not


yes the direction is always changing
