Vectors,scalars And Graphs Of Motion

physical quantities that have magnitude only such as time,mass and charge Scalar quantities can just be added or subtracted

Physical quantities that have both magnitude and direction such as force and wait vector quantities can just be idle subtracted but they need to be added or subtracted algebraically as they have a direction

Negative factors have the same magnitude as a positive vector a travel in the opposite direction negative scalars have a much smaller magnitude

They combined effort of a number of vectors the resultant is the vector quantity that has the same effect as two or more vector quantities

Change in position of the body with respect to time

A set of reference points such as the set of access that enables the position of an object to be defined at any time

Plotted relative to a reference point or Arjun it is Vector quantity

Motion along a straight line and can be either in One Direction or the opposite direction

The length of the path that an object moves along from one position to another it is the scaler quantity and is represented D ,it is measured in metres

Change in position it is the magnitude and direction of a straight line drawn from the initial to final point it is a vector quantity and is represented as delta X or delta Y is measured in metres in a certain direction

You don’t displacement equals X final minus X initial so Delta X= Xf-Xi

Total distance travelled divided by the total time the constant speed message through for a car to travel the distance in a certain time

Average speed = distance/time it is measured in metres per second it is Scalar quantity and has magnitude only it is the quotient of two scalars

You displacement or change in position divided by the total time taken the last has both magnitude and direction

V=delta X/ delta t It is measured in metres per second in a direction

Divide by 3, 6

Change in velocity divided by time taken

A = delta V/delta t It is measured in metres per second squared in a direction as it is a vector quantity

In one dimensional motion positive and negative in opposite directions positive exhilaration is what we commonly term acceleration and negative acceleration is what we term deceleration

Delta Y/Delta X

Displacement divided by an infantismal time interval is a vector quantity the gradient of a tangent of a point on a position time graph formula is V equals delta X/Delta T it is measured in metres per second in a direction

Same as the magnitude of instantaneous velocity

Measurable property of something we find in nature

Stationery so V=zero is a straight horizontal line Constant velocity forwards is a straight line up to the right hand corner Constant velocity backwards is a straight line down from the left-hand corner Increasing velocity so positive acceleration is a curved graph from nought up to the right hand corner Decreasing velocity so negative acceleration is a curve graph from nought up to right hand corner so that looks like a sun Gradient = velocity
