9.81 m/s2 is the acceleration of an object in free fall, responding only to gravity
with no other forces on it, on or near the Earth's surface ... otherwise known as
the acceleration of gravity.
It's always true on or near the surface of the Earth ... if you can provide those
conditions: No other forces except gravity acting on the falling object, including
no air resistance !

What is the velocity of a car increases by 40 ms in 80 seconds. What is the acceleration of the car A. 0.5 ms2 B. 0.25 ms2 C. 120 ms2 D. 40 ms2?
The acceleration of the car can be calculated using the formula: acceleration = (change in velocity) / time. In this case, the change in velocity is 40 m/s and the time is 80 seconds. Therefore, acceleration = 40 m/s / 80 s = 0.5 m/s². So, the correct answer is A. 0.5 m/s².
A rock at rest has weight 138 N. What is the weight of the rock when it is accelerating downward at 3.5 ms2?
When the rock is accelerating downward at 3.5 m/s^2, its weight remains the same at 138 N regardless of acceleration. Weight is a measure of the force of gravity acting on an object, and in this case, the weight is constant regardless of any acceleration the rock experiences.
What i the SI unit for force which is equal to 1 kg ms2?
The SI unit for force that is equal to 1 kg m/s^2 is the newton (N).
What is meant by an acceleration of -2 ms2?
An acceleration of -2 m/s^2 means that the velocity of an object is decreasing by 2 meters per second every second. The negative sign indicates that the acceleration is in the opposite direction of the velocity.
How much force is needed to accelerate a 9760 kg airplane at a rate of 4.7 ms2?
The force needed is 45,872 N. This is calculated by multiplying the mass of the airplane (9760 kg) by the acceleration (4.7 m/s^2).
The quantity 2 ms2 is a measure of?
acceleration
What is the velocity of a car increases by 40 ms in 80 seconds. What is the acceleration of the car A. 0.5 ms2 B. 0.25 ms2 C. 120 ms2 D. 40 ms2?
The acceleration of the car can be calculated using the formula: acceleration = (change in velocity) / time. In this case, the change in velocity is 40 m/s and the time is 80 seconds. Therefore, acceleration = 40 m/s / 80 s = 0.5 m/s². So, the correct answer is A. 0.5 m/s².
What force would it take to accelerate a 900kg car at a rate of 6 ms2?
5,400
Where can one find information about the bacteriophage MS2?

How much force is needed to accelerate your body at a rate of 2 ms2 if you weigh 45 kg?
90 N
What force is needed to give an 7900 kg truck an acceleration of 8.9 ms2?
The force required is 70,310 newtons.
What is the mass of a truck if it is accelerating at a rate of 5 ms2 and it hits a parked car with a force of 14000 newtons?
fu
