## When a car is traveling in a straight line at a constant speed its acceleration is?

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 formula for a car accelerates from rest at a constant rate alpha?

From the above equations we get, t1=vα&t2=vβt1+t2=t=vα+vβ⇒v=αβα+βt. Was this answer helpful? A car starting from rest, accelerates at a constant rate α for some time after which it decelerates at a constant rate β to come to rest.

## 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 is acceleration when the line is straight?

Answer and Explanation: If the line on the graph is straight that means that the acceleration is constant. If the graph is horizontal acceleration =0.

## What is the formula for acceleration of a moving car?

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

## What is the formula for acceleration of a car?

## What is the formula when acceleration is constant?

Since the acceleration is constant, we have a=v−ut. This gives the first equation of motion, v=u+at.

## Is acceleration zero in a straight line?

So, a jet moving with a constant velocity at 800 miles per hour along a straight line has zero acceleration, even though the jet is moving really fast, since the velocity isn’t changing.

## What is moving in a straight line called?

The correct option is A rectilinear. The type of motion in which a body moves in a straight line is called ‘rectilinear motion’.

## Is acceleration always a straight line?

When a body is subjected to a uniform acceleration, it always move in a straight line.

## Does constant speed in a straight line mean no acceleration?

If a body is moving with constant speed in a circle, then yes, that body has acceleration. However, if the body is moving with constant speed in a straight line, then no, that body has no acceleration. This is because acceleration measures the change in velocity, and velocity is speed with a direction.

## 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.
