When you change your straight-line velocity (speed) from slow to fast you have positive acceleration and from fast to slow it will be negative acceleration.
Acceleration = velocity change divided by time taken.
So when you are traveling at say 10 m/s and decelerate to zero in 5 seconds, your (negative) acceleration will be = (0-10)/5 = - 2 metres per sec per sec.
Normally expressed as -2m/s^2.

What will the stopping distance be for a kg car if -3000 N of force are applied when the car is traveling 10ms?
To calculate stopping distance, we need to first find the deceleration of the car using the formula: force = mass x acceleration. Given that force = -3000 N and mass = kg, we can find the acceleration. Once the acceleration is known, we can use the equation of motion: final velocity^2 = initial velocity^2 + 2 x acceleration x distance to calculate the stopping distance.
What will the stopping distance be for a -2000 N of force are applied when the car is traveling 20 ms?
To calculate the stopping distance, we need more information such as the mass of the car and the acceleration. The force alone is not sufficient to determine the stopping distance.
What is the average acceleration of an elevator when starting and stopping?
The average acceleration of an elevator when starting and stopping can vary, but it is typically around 1 m/s^2. This acceleration allows the elevator to move smoothly while ensuring the comfort and safety of the passengers.
What will the stopping distance be for a 3000-kg car if -3000 N of force are applied when the car is traveling 10 ms?
To calculate the stopping distance, we need to know the deceleration of the car, which can be determined using the equation force = mass x acceleration. In this case, the deceleration would be -1 m/s^2. Using the equation stopping distance = (initial velocity)^2 / (2 x acceleration), we find the stopping distance to be 50 meters.
What is positive and negative acceleration?
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
What would happen to the acceleration if you increased the mass?
the acceleration decreases

When a body stops mooving what happen to the acceleration?
Acceleration becomes zero.
How do you find retardation if speed of a bus and its stopping time interval is given?
Reteradation will be half of acceleration
Suppose the force F doubles what will happen to the acceleration?
acceleration doubles too.
When do acceleration happen?
when there is change of speed

Can acceleration happen on a frictionless surface?
yes
What is horizontal acceleration?
It is acceleration in the horizontal direction. This would happen as a result of a net horizontal force acting on a body.
What happen to the acceleration of an object if the force one object increases?
Acceleration is a net force that is inversely dependent on mass, therefore if an object mass increases ,acceleration decreases
