Topic 1.1 and 1.2 Flashcards
Acceleration equation
velocity change ÷ time taken
or
change in speed ÷ change in time
Weight definition (w)
Gravitational force on an object with mass (N)
Velocity equation
Velocity= Displacement ÷ Time
Mass definition (m)
quantity of matter present in a substance (kg)
Slope/Gradient equation
Rise ÷ Run
Are of a circle
pi x r²
Equation for speed
Speed= Distance ÷ Time
Volume
Length x breadth x height
Speed meaning
How fast something goes in any direction
Acceleration meaning
Rate of change in velocity (m/s²)
Distance
How far and object moves
(scalar- no direction)
Displacement definition
shortest distance between two points
(vector- magnitude and direction)
Velocity meaning
How fast an object moves in a particular distance (m/s)
Density definition (D)
Ratio of mass to volume (kg/m³) (g/cm³)
Equation for Weight (w)
Mass (m) x Gravity (g)
Area of a triangle
1/2 x base x height
Equation for Density
Mass (m) ÷ Volume (v)
Volume of cylinder
pi x r² x h
Vectors meaning
Needs both magnitude and direction to define them.
eg. Force, velocity
Motion definition
The movement of an object through space
Speed definition
How fast and object moves from one place to another
