What are the types of motion?
- Translational Motion
- Uniform Velocity
- Motion with Constant Velocity
It is the rate at which an object changes its position in a specific direction. It tells you the speed and where the object is headed.
Velocity
It is the rate at which the velocity changes. If you speed up, slow down, or turn, you are accelerating
Acceleration
A type of motion in which an object moves from one position to another, and all parts of the object move the same distance in the same direction at the same time.
Translational Motion
Translations motion can occur?
- In a straight line
- Along a curved line
What are the types of Translational Motion
- Rectilinear Motion
- Curvilinear Motion
An object is said to have this velocity if you move with constant speed in a straight line, and its direction does not change
Uniform Velocity
When an object moves with uniform velocity:
- It covers equal distances in equal intervals
- It does not speed up or slow down
- It does not change direction
- Its acceleration is zero
Examples of Rectilinear Motion:
- A car moving along a highway
- An elevator moving up and down
- A train moving straight on a railway track
Examples of Curvilinear Motion:
- A thrown ball moving in a curved path.
- A car turning around a curved road
- A satellite orbiting the Earth
Examples of Uniform Velocity:
- A train moving at constant speed on a straight track
- A person walking straight at a steady pace.
- An escalator moving upward at a constant speed
- A conveyor belt moving at a constant speed.
Velocity is a vector quantity, which means it has?
-. Magnitude (speed)
- Direction
Uniform velocity means:
- No change in speed + No change in direction = no Acceleration
An object accelerates when:
- It speeds up
- It slows Down
- It changes direction
- Velocity changes by the same amount in equal time intervals
- Acceleration remains constant
- The object may move in a straight or curved path.
Motion with constant acceleration
Examples of Motions with Constant Acceleration
- Free Fall
- A car Speeding Up Uniformly
- A car Slowing Down uniformly
- A Ball Rolling Down A slope
Constant Acceleration means:
Velocity is changing steadily, not randomly.
If two objects interact in two perpendicular directions, the total momentum of the two objects before the interaction is the same as the total momentum after the interaction in both directions.
COnservation of Momentum in two Direction
When two objects interact in a single direction, the total momentum of the two objects before the interaction is equal to the total momentum after the interaction.
Conservation of Momentum in One Direction
What is the equation for Translational Motion with Constant Velocity?
velocity = distance/time
What is are the used units for Translational Motion with Constant Velocity?
Velocity = m/s
Distance = m
Time = s
What are the equations for Translational Motion with Constant Acceleration?
- Final Velocity = Initial Velocity + (acceleration)(time)
- Final Velocity^2 = Initial velocity ^2 + 2(acceleration)(distance)
- Distance = (Initial velocity)(Time) + 1/2(acceleration)(time)^2
What are the units used for Translational Motion with Constant Acceleration?
Initial & Final Velocity = m/s^2
Acceleration = m/s
time = s
distance = m
