Motion and forces Flashcards
what is a vector
give 4 examples of vectors
what is velocity
The velocity of an object is its speed in one particular direction
what does a distance time graph show
what does a velocity time graph show
what is a free body force diagram
how do you calcualte speed
distance/time
what happens when two bodies interact
what does the acceleration produced by a resultant force depend on
use equations
do questions
Investigate the relationship between force, mass and acceleration
what happens in a vacuum of bodies falling
all falling bodies accelerate at the same
rate
define mass
define weight
Demonstrate an understanding that: a) when an object falls through an atmosphere air resistance increases with increasing speed b) air resistance increases until it is equal in size to the weight of the falling object c) when the two forces are balanced, acceleration is zero and terminal velocity is reached
