### Is the force the speed?

###### Asked in Science, Math and Arithmetic, Physics

### How can the equation force equals mass x acceleration be rewritten?

Equation: Force=Mass X Acceleration
If you are looking for the force, use the equation as is.
To find the following, it's assumed that you are given the other
two values:
Mass= Force / Acceleration
Acceleration= Force / Mass
Remember your labels in your calculations.
Mass= force x acceleration
Force = mass x acceleration
mass = force / acceleration
acceleration = force / mass
Since acceleration = velocity / time we can also substitute
velocity / time for acceleration in any of the above.
Since velocity = speed / time, we can also substitute speed /
time for velocity or speed / (time * time) for acceleration in any
of the above.

###### Asked in Physics

### What situation is there in which you can accelerate even though your speed doesn't change?

no because acceleration is the increase in velocity or
speed.
Answer:
in the case of linear acceleration the speed must be increasing
or decreasing to produce acceleration However, centripetal
acceleration is acceleration that comes from a force that is not in
a straight line, when the object moves circular pattern with
radius, r. Unlike linear acceleration which has the acceleration in
the direction of the applied force, centripetal acceleration has an
acceleration tangential to the force. it is perpendicular to the
line of movement

### What is related to force?

###### Asked in Mechanics

### What is the Formula for Force required to accelerate an object to a predetermined speed?

There is no specific force required to accelerate an object to a
predetermined speed.
A smaller force will produce a smaller acceleration, so it will
take longer to reach the desired speed.
A larger force will produce a larger acceleration, so the
desired speed will be reached sooner.
But either the large or the small force, or any other force,
will produce an acceleration, and cause
the object to reach the specified speed sooner or later.

### An example of zero acceleration would be what?

If you are moving at a speed of ceratin speed and there is no
force trying to slow you down, and there is no force trying to
speed you up. Then there is zero acceleration. An example would be
: an object in out in space, if you throw a object away from you
the object will float away, since there is no force working on the
object after you throw it the object is moving away in a locked
speed from you, but have zero acceleration because there is no
force affecting the object

###### Asked in Physics

### Why an object moving in a circular path at a constant speed is undergoing acceleration and has a force excert on it?

-- An object with no net force on it continues moving at
constant speed in a straight line.
If it's not moving in a straight line, then there must be net
force acting on it.
-- "Acceleration" is the word for the situation where either
speed or direction of motion changes.
Even if speed is constant, acceleration is present if the
direction is changing.

###### Asked in Physics, Calculus

### How are constant speed and constant acceleration different?

There is a huge difference between constant speed and constant
acceleration. Constant speed is when the object is travelling
constant, no change in its velocity and acceleration or in other
words no extra force to speed up.
Constant acceleration when the object is acceleration constant,
it means that the speed of the object is change at the same rate
each second. The acceleration rate at which the object is
travelling is constant.
for example, when a car is stationary at a traffic light and it
starts acceleration, picking up speed but the rate of acceleration
will not constant because the amount of force applied differs each
second due to the acceleration rate.
