Flashcards do conjunto (28)
- 1What is the distance? What are its units?It is how far an object has traveled from the start, and is measured in m/s.
- 2What is the difference between scalar and vector quantities?Vectors have MAGNITUDE (size) AND DIRECTION Scalars have only MAGINITUDE
- 3List examples of scalar quantities.distance, time, speed, work, power
- 4List examples of vectors.displacement, acceleration, velocity, force,
- 5True of False?: Only somethings are measured in either a scalar or vector quantitys.FALSE
- 6What is acceleration? What factors are present?It is the speed at which an object travels
Factors: accelerating= change in speed or velocity - 7What is the formula to calculate Acceleration?A= initial speed-final speed/time
- 8What is speed?the measure of how far an object has moved
- 9true or false?: velocity is a measure of how fast something is moving, and in what directionTrue
- 10What is the formula to measure speed and velocity?(v) speed=distance (s)/ time (t)
(v) velocity= displacement (s)/ time (t) - 11VELOCITY VS. TIME GRAPHS!! Fill in the gaps: a straight line sloping upwards indicates___________.acceleration
- 12VELOCITY VS. TIME GRAPHS!! Fill in the gaps: The are under the graph represents the _________.slope
- 13VELOCITY VS. TIME GRAPHS!! Fill in the gaps: The gradient of the graph give the ___________ of the object.acceleration
- 14VELOCITY VS. TIME GRAPHS!! Fill in the gaps: A horizontal line sloping downwards indicates _____________.Deceleration
- 15VELOCITY VS. TIME GRAPHS!! Fill in the gaps: a HORIZONTAL line indicates _____________.constant speed
- 16what does a distance vs. time graph represent?the distance of an object at a particular time
- 17What does this represent?: a line that is constant and straightstationary
- 18DISTANCE VS. TIME GRAPH--What does this represent?: a line that is sloping upwards...acceleration
- 19DISTANCE VS. TIME GRAPH--What does this represent?: a line that is sloping downwarddecceleration
- 20How do your find the distance traveled on a velocity vs. time graph?Find the area of shapes that create the lines
- 21True or False: A person makes a round trip and she finishes where she began. The displacement for the trip is 0 and the distance is some non-zero value.as true as the color blue babyy :)
- 22A vector quantity is large and a scalar is smallFalse, vice versa
- 23How many dots does a ticker timer make per second?50
- 24If the dots on a ticker timer tape get further apart, what does this mean?The object is accelerating faster and faster.
- 25What does it mean if the dots on the tape are consistent in each section?The object is moving at a constant speed.
- 26What is the formula for acceleration?acc.=initial-original/ time
- 27what does the slope of a Distance vs. Time graph represent?velocity
- 28what does the gradient on a Veloctiy vs. Time graph rep?Acceleration
