Linear motion Flashcards
Speed definition?
Rate of change of position
Distance definition?
Path a body takes from start to finish
How do you work out distance?
Speed x time
Velocity definition?
Rate of change of displacement
Mass definition?
Quality of mater a body has
Weight definition?
Mass x gravity
Displacement definition?
Shortest route from start to finish in a straight line
Acceleration definition?
Rate of change of velocity
Momentum definition?
Product of mass and velocity
Impulse definition?
Time a force is applied
Who do you work out impulse?
Force x time
How do you work out velocity?
Displacement / time
How do you work out acceleration?
Change in velocity / time
How do you work out momentum?
Mass x velocity
How do you work out speed?
Distance / time
What are the factors that affect friction?
Temperature of the surfaces, surface characteristics, mass of the object
What affects air resistance?
The velocity of the moving body
Cross sectional area
Shape and surface characteristics
What does a straight line indicate on a velocity time graph?
Constant speed
What does the velocity time graph indicate when the lines goes beneath the x axis?
Change in direction
What does a straight line indicate of a distance time graph?
Stationary
