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

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.
