A force 10 N pushes a mass of 4 kg to the right At the same time another force of 2N pushes the same mass to the left What is the magnitude size and direction of the resulting acceleration of the?
Sykotic2002
The masses are colinear, so we can simply add them together. Assuming to the right is the positive direction, the 10N force is written +10N, then to the left is negative, so the other force is -2N.
The sum of the forces = +8N, or 8 N to the right. One newton is equal to kg*m/s2.
Acceleration is force / mass, or 8/4 or 2 m/s2 in the positive direction, or to the right.

This is a quantity that has both size and direction?
Such a quantity is called a vector. A shining example is velocity itself. velocity is the rate of change of displacement- the distance moved by particle in a specified direction. Since velocity = displacement/time taken = vector/scalar, Velocity thus has both a direction and a magnitude (magnitude = speed of particle) Another examples include quantities such as Force, acceleration, displacement
What two things does a vector quantity have?
In order to have a vector quantity, one needs to have some sort of magnitude and a direction. An example of this is velocity. Velocity is a speed in a certain direction, so velocity is a vector, but speed is not. These words are commonly misused in society, and used interchageably with one another.
What do you call a FORCE twice as large as another force acting at right angles with it?
Acceleration with magnitude of (f1^2 + f2^2)^(1/2) @ 45degrees from either direction towards the other
What type of quantity is acceleration?
Acceleration is a vector quantity with both magnitude and direction components. It describes a change in velocity, another vector quantity.The presence of two components distinguishes it from a scalar quantity, like speed, that only has one component (velocity and speed are different).
Why is the velocity of the car traveling in a circle changing?
Because "velocity" consists of a speed and a direction. If the direction is changing, then the velocity is changing, even though the speed isn't. And here's another one for you: "Acceleration" means any change in velocity. So if the race car is going around an oval track at a constant speed, it's accelerating. ==> Because its velocity is changing. ==> Because its direction is changing. ==> All at constant speed.

What is the magnitude of a force of 117.4 moving upward and another force of 74.1 moving downward?
the magnitude is 43.3 and the direction is upward.
What is another name for acceleration when velocity increase?
When the magnitude of velocity increases, many people call that "speeding up".
Explain the difference between positive and negative acceleration?
well the difference between positive and negative velocity would have to be that if your motion speeds up than you have a positive and when or if your motion slows down then you would have a negative accelerarion!!!!
Why an object in a circular orbit at constant speed is experiencing an accelaratiopn?
An object in circular orbit at constant speed is experiencing an acceleration because the orbit is circular. That is, an object is accelerating not just when its speed is changing but also when its direction is changing. In physics, acceleration refers to a change in velocity which is composed of speed and direction. Hence both a change in speed and a change in direction are, by definition, a form of acceleration.
When does a cyclist appear to be stationary with respect to another moving cyclist?
when their velocity vectors are in the same direction and same magnitude

What change the direction of the force?
the exertion of another force
How can you change an objects velocity?
Yes - speed is rate of change of position irrespective of direction. What an object cannot do is change direction without changing velocity, which is speed in a particular direction, i.e. a vector rather than a scalar. In vector terms, speed is the modulus of the velocity vector. An example would be a body in gravitational circular orbit around another body - constant speed, but continuously changing velocity due to the gravitational force.
