What are the three formulas you can use for uniform acceleration?
The relations between these quantities are known as the equations of motion. In case of uniform acceleration, there are three equations of motion which are also known as the laws of constant acceleration….The three equations are,
- v = u + at.
- v² = u² + 2as.
- s = ut + ½at²
What is the formula for uniform acceleration?
Summary. Acceleration that does not change in time is uniform, or constant, acceleration. The equation relating initial velocity, final velocity, time, and acceleration is vf=vi+at.
What are some examples of uniform acceleration?
Some uniform accelerated motion examples include a ball rolling down a slope, a skydiver jumping out of a plane, a ball dropped from the top of a ladder and a bicycle whose brakes have been engaged.
What is uniform acceleration write with example?
Uniformly Accelerated motion : When a body moves along a straight line and its velocity increases by equal amounts in equal interval of time then the motion is called uniformly accelerated motion. E.g.:- Motion of a freely falling body.
What is uniform acceleration Class 9 Example?
A body has a uniform acceleration if it travels in a straight line and its velocity increases by equal amount in equal intervals of time. For Ex:Motion of freely falling body, bicycle going down the slope, ball rolling down in inclined plane.
Which of the following is example of non uniform acceleration?
Examples of non-uniformly accelerated motion : 1- The motion of a bus leaving or entering the bus stop. 2- The motion of a train leaving or entering the platform. 3- The motion of a bus on a crowded road.
What are the examples of uniform acceleration and non uniform acceleration?
Five real life examples of uniform and non uniform acceleration?
- The motion of freely falling body .
- Motion of ball in a plane.
- Motion of tip of minute hand.
- Motion of earth around the sun..
- motion of car with constant velocity.
What are the examples of uniform velocity?
Uniform Velocity
- The rotation of the Moon around the earth.
- Movement of hands of a watch.
- Rotation of Earth.
- Revolution of Earth.
What is meant by uniform circular motion write one example?
(a) When a body moves in a circular path with uniform speed (constant speed), its motion is called uniform circular motion. For e.g. (i) Artificial satellites move in uniform circular motion around the earth. (ii) Motion of a cyclist on a circular track.
What are the formulas for speed velocity and acceleration?
Key Equations
| Displacement | Δx=xf−xi |
|---|---|
| Average speed | Average speed=–s=Total distanceElapsed time |
| Instantaneous speed | Instantaneous speed=|v(t)| |
| Average acceleration | –a=ΔvΔt=vf−v0tf−t0 |
| Instantaneous acceleration | a(t)=dv(t)dt |
