Uniform Motion

How can uniform motion be

I. Any object moving at a constant velocity

expressed and how can it be

II. When graphed, the line of best fit represents the average speed

a. y = mx + b; where “m” is the constant (slope) and “b” is the initial

calculated?

value

b. velocity = displacement / time (m/s)

Vectors and Scalars

What is the difference betw-

I. A vector is a measurement that has a direction component

een a vector and a scalar?

a. Velocity and displacement are vector quantities (e.g. 5 km/h [S])

II. Speed and distance are scalar quantities (e.g. 15 m away)

Uniform Acceleration

What is uniform acceleration

I. Accelerated motion (non-uniform) occurs when an object travelling in a

and how can it be calculated?

straight line changes its speed uniformly with time

II. Non-uniform acceleration occurs when an object changes its speed in a

non-uniform fashion

III. Acceleration can be calculated (vector quantity)

How is instantaneous accel-

a. Average acceleration = change of velocity / time interval (m/s

) or

can be = (final velocity) – (initial velocity) / time interval

eration different and how can

It be calculated?

b. Instantaneous acceleration is the acceleration at a particular instant

and can be found using tangent lines on graphs. This will appear as

a curved slope on a graph

Graphs

What are the three different

I. Position-time graphs

types of graphs and what

a. The slope of the graph equals velocity

do the different parts repre-

b. When the velocity is changing, the slope is a curve

sent?

II. Velocity-time graphs

a. The area underneath any section of the graph equals displacement

b. The slope of the graph equals average acceleration

II. Acceleration-time graphs

a. The acceleration is zero when the motion is uniform

b. Represented by a horizontal line when motion is non-uniform

c. The slope equals the change in acceleration over time

To draw a tangent, choose a point on the graph, and then draw a straight

line that does not touch any other part of the graph

Uniform motion is motion at a constant velocity. * velocity = displacement / time * Uniform

acceleration is when an object changes its velocity uniformly. * a

Instantaneous acceleration is the acceleration of an object at a certain instance during non-uniform

acceleration; this can be found by drawing tangent lines and calculating the slope of the tangent.

Position-time graphs, velocity-time graphs, and acceleration-time graphs can all represent those

three quantities using slopes and shapes of the line or curve of best fit.
