A single force of 40 N acts upon a 5-kg block- what is the magnitude of the acceleration of the block?

F=MA so F = 40 and M = 5 so 40= 5 x A therefore A = 8 meters per second squared.

What affects the acceleration of an object?
An object's acceleration is the result of a force being applied to it. When that happens, the magnitude of the resulting acceleration is equal to the force divided by the object's mass, and the direction of the acceleration is in the direction of the force.
Why is it necessary to observe uniform motion of the block in each procedure?
Uniform motion means no acceleration.No acceleration means that there is no net force acting on the block.If there is no net force then the magnitude of the kinetic friction force is equal to the component of the weight force.
Does negative acceleration have constant acceleration?
Not necessarily so. Negative (deceleration) could be growing or decreasing in magnitude. The cause is going to be the Force that is acting on the system. If the Force is increasing, the acceleration will be also.
How do you change centripetal acceleration?
Change the magnitude of the force attracting the object toward the center.
How would the observed value of the acceleration of a block be affected if the one used is heavier?
From f = m*a, a = f/m, so if the force remains constant and the mass increases, the acceleration will decrease. But if the block is on an incline and the force is provided by gravity, the force will increase directly proportional to the mass of the block, and acceleration will remain the same.

When a force on an object increases how does the object acceleration change?
Changing the magnitude or direction of forces exerted on an object changes the net force (sum of all forces) exerted on the object. The net force exerted on an object is defined as mass times acceleration (F = ma), where mass, m, is constant. This means that when the net force exerted on the object changes in magnitude (or direction), its acceleration will also change in magnitude (or direction). In addition, acceleration is defined as the change in velocity, so when the magnitude (or direction) of acceleration changes, the magnitude (or direction) of velocity will also change.
What is the acceleration of a 37kg block when pulled by a force of 170 N?
The acceleration in the block will be 4.59 m/s2

Uniform motion means no acceleration.No acceleration means that there is no net force acting on the block.If there is no net force then the magnitude of the kinetic friction force is equal to the component of the weight force.

What is the direction of acceleration when moving in a circle?
The direction of the acceleration is towards the center. The magnitude of the acceleration is v2/r.
How do you change centripetal acceleration?
Change the magnitude of the force attracting the object toward the center.
What are the magnitude and direction of action and reaction forces?
the force of action and the force of reaction are of equal manitude and work in the opposite divections

Can you have a net force when the forces applied to the objects are balanced?
Yes, you will have a net force but its magnitude is zero if it does not cause any acceleration.
Is centripetal acceleration a uniform acceleration give reason?
No it is not because its direction is constantly changing. It is not a constant force. Force has direction as well as magintude and while it magnitude is constant its direction is not.
A car is moving with constant speed and yet the acceleration and net force are not equal to zero how is this possible?
It's not possible. Acceleration is defined as a change in velocity, so if the speed is constant, the acceleration is zero. If the acceleration is zero, so is the net force.
