The total mass and the force exerted on it.
The formula is F=ma - a=F/m, F is the resultant force acting on the body, m is the mass of the body, and a is its acceleration

∙ 13y agoThe two components of velocity, like any vector quantity, are its magnitude (size) and its direction. This is different from speed, a scalar quantity, which only has magnitude.
An example of velocity is 25 miles/h North.
An example of speed is 50 km/h.

v: velocity
s: distance
t: time
the velocity of an object is determined by the distance the object covered divided by the time it took the object to cover the whole distance.
Wiki User
∙ 10y agothere actually is three factors. since velocity is a vector quantity, it has a magnitude and a direction. you need the time, distance traveled over that time and the direction. ie: 5mph to the north.

What two things must you know to determine average speed?
To determine average speed, you need to know what distance the object traveled in meters over how long it took the object to travel that distance in seconds.
What must you calculate to determine the acceleration of an object?
You must calculate the change in velocity during each unit of time.
How do you find acceleration from speed?
If speed does not change, then acceleration is 0 To find acceleration, you must also know the time Speed = metres per second. Acceleration = meters per second, per second Therefore you can use the equation m/s2 to find the acceleration. change in speed/ change in time.
Velocity provides information about what?
Velocity is a vector quantity, which means it is made up of more than one numeric value. Velocity vectors must contain information on speed and direction.
What is required to change velocity of an object?
In order for an object to travel with constant velocity the sum of forces acting on it must be 0 N. According, to Newton's second law, ΣF = ma where ΣF is the sum of forces m is mass a is acceleration If the acceleration is not 0, then the object is not traveling at a constant velocity. In order for a to equal 0, the sum of forces must be 0 because by solving Newton's second law for a, we get a=ΣF/m If ΣF is not 0, then that equation will never allow a to equal 0 and the object will b accelerating. Therefore, the sum of forces must equal 0 for an object to travel with constant velocity.
What three things must you know to determine velocity?
Just speed & direction.
To determine acceleration you must know the change in velocity during each unit of what?
"time"
What must you know to determine which two vehicles traveling at the same velocity has the greater momentum?
You need to know their mass. p=mv momentum=Mass times Velocity
What must you know to determine which of two vehicles traveling at the same velocity has the greater momentum?
You need to know their mass. p=mv momentum=Mass times Velocity
In order to determine speed you must know two things?
distance and time
What two things must you know determine average speed?
distance and time
What must you calculate to determine the accerleration of an object?
To determine the acceleration of an object, you must calculate its change in velocity per unit of time.
What 2 things must you know to descriobe the motion of an object?
If movement is in two dimensions: the x-coordinate of the velocity, and the y-coordinate of the velocity. Or alternatively: the magnitude of the velocity, and the direction. If movement is in three dimensions, you need to know three things, for example, x-coordinate, y-coordinate, and z-coordinate of the velocity, or magnitude of the velocity and two components of direction.
What must be included when reporting an objects velocity-?
Speed and direction of motion are needed to determine velocity.
What two things must you know to determine average speed?
To determine average speed, you need to know what distance the object traveled in meters over how long it took the object to travel that distance in seconds.
What are two things must you know to determine average speed?
Total distance/total time
What must you calculate to determine the acceleration of an object?
You must calculate the change in velocity during each unit of time.
