## What is motion along a straight line called?

Linear motion is the motion in which a body moves along a straight line.

## What is the acceleration of a bus moving along a straight line at 20 meters per second?

A bus moving along a straight line at 20 m/s undergoes an acceleration of 4m/s2.

## What is moving in a straight line?

Motion in a straight line is called straight motion. If the direction of a moving object is constant and the object is moving at a constant speed, then it is moving in a straight line. In this case, the object is said to be moving in a straight line at constant speed.

## What can you say about the speed and velocity of a body moves along a straight line?

Therefore, the speed and velocity of the body is equal when the body moves without any change in direction or moves in a straight line motion.

## What is the motion along a straight line called Class 9?

Movement of any object from one position to another position with respect to the observer is called as Motion. Motion Along a Straight Line: When an object moves along a straight line, the motion of the object is called rectilinear motion.

## What is motion along a straight line called Class 11?

We shall confine ourselves to the study of motion of objects along a straight line, also known as rectilinear motion.

## What is the acceleration moving along a straight line?

The acceleration of a particle moving along a straight line at any time t is given by a=4-2v , where v is speed of particle at any time t.

## Which is the correct formula for straight line acceleration?

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.

## What is the acceleration of a straight line?

If the equation of the motion is linear, then the velocity is constant and if velocity is constant, then acceleration is zero.

## What are the 10 examples of straight line motion?

- Ten examples of straight line motion are :
- (1)A moving car in straight line.
- (2) Parades of Army.
- (3) Free fall of any object.
- (4) Falling fruits from trees.
- (5) A train travelling on straight track .
- (6) Up and Down lifting.
- (7) Rockets launch.

## What is an example of a straight line in physics?

While straight lines have no definite beginning or end, they are represented in our day-to-day lives with examples such as railway tracks or the freeway.

## What is the formula for an object moving in a straight line?

Displacement | Δx=xf−xi |
---|---|

Instantaneous acceleration | a(t)=dv(t)dt |

Position from average velocity | x=x0+ˉvt |

Average velocity | ˉv=v0+v2 |

Velocity from acceleration | v=v0+at(constanta) |

## When the object is moving along a straight line at constant speed?

Uniform motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time.

## When a body is moving in a straight line with a uniform velocity?

If a body is moving in a straight line at a constant velocity, then no forces are acting on the body.

## What is the SI unit of velocity?

The SI unit of velocity is metre per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).

## What is the momentum of a car traveling in a straight line at 20 m sec?

The momentum of a car traveling in a straight line at 20 m/sec is 24,500 kg·m/sec.

## What is the acceleration of a car traveling at a constant rate in a straight line?

Explanation: Acceleration is defined as the rate of change of velocity. In the given problem the car travels in a straight line at a constant speed. Or there is zero acceleration of the car.

## What is the acceleration of a car that travels in a straight line in a constant speed?

The acceleration is zero. You’ve already defined the acceleration by stating that the car is traveling at a constant speed. Acceleration is defined as a change in rate over time and since the speed is constant, there is no change in rate.

## What is the acceleration of a car that travels in a straight line at a constant speed of 80 km h?

Since the car is traveling at a constant velocity, its acceleration is zero.
