What is motion along a straight line called?

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.
