Translational Motion and Linear Quantities

Motion

a change in position of an object over

time.

Distance

total length of the path transversed between initial and final positions.

dtotal = d1 + d2

What is the formula of distance?

Displacement

it is the length of the shortest path between initial and final position with direction

What is the formula of displacement?

Speed

is a scalar quantity that measures how fast the object is moving regardless of direction.

What is the formula of speed?

Velocity

is a vector quantity that describes both speed and direction of the object

What is the formula of velocity?

Acceleration

The rate at which velocity changes (speeding up, slowing down, or changing direction).

What is the formula of Acceleration?

1. Linear Displacement

2. Linear Velocity

3. Linear Acceleration

Linear Quantities

Linear Displacement

The straight-line distance from the starting point to the ending point with direction.

Linear Velocity

The speed/rate of an object in a given direction.

Linear Acceleration

The rate at which velocity changes (speeding up, slowing down, or changing direction).

Translational Motion

is a type of motion where an object moves from one point to another without rotating about its own axis

1. All points on the body travel the same displacement.

2. All points on the body travel in the same direction.

3. All points on the body travel with the same duration (time).

4. All points on the body travel with the same velocity.

5. All points on the body travel with the same acceleration.

Characteristics of Translational Motion

Rectilinear Motion

displacement, velocity and acceleration of an object moves along in straight line.

Curvilinear Motion

displacement, velocity and acceleration of an object moves along in curved path.
