What else can I help you with?
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?
To determine velocity, you must know the object's distance traveled, the direction in which it traveled, and the time it took to travel that distance. Velocity is a vector quantity that includes both speed (magnitude) and 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 two things must you know in order to describe velocity?
To describe velocity, you need to know the speed of an object and its direction of motion. Velocity is a vector quantity that includes both magnitude (speed) and direction.
What must you know to determine speed?
To determine speed, you must know the distance traveled and the time taken to cover that distance. Speed is calculated as distance divided by time. You may also need to know the direction of motion if you want to determine the velocity, which includes both speed and direction.
What two things must you know determine average speed?
distance and time
What information must you know to determine which of 2 vehicle traveling at the same velocity has the greater momentum?
To determine which of two vehicles traveling at the same velocity has greater momentum, you need to know the mass of each vehicle. Momentum is calculated by multiplying an object's mass by its velocity, so the vehicle with greater mass would have greater momentum if they are traveling at the same velocity.
What do you need to know to determine momentum?
To find the momentum of an object you must know the mass of the object and the velocity at which it travels. Example: A 50kg man runs at 10m/s. What is his momentum? Momentum = Mass x Velocity 50 x 10 = 500 kgm/s
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 you calculate to determine the accerleration of an object?
To determine the acceleration of an object, you need to calculate the change in velocity over a specific period of time. Acceleration is calculated by dividing the change in velocity by the time taken for that change to occur. The formula for acceleration is acceleration = (final velocity - initial velocity) / time.
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 know to determine which of two vehicles traveling at the same velocity has the greater momentum?
To determine which vehicle has the greater momentum, you need to know the mass of each vehicle. Momentum is defined as momentum = mass x velocity, so the vehicle with the greater mass will have the greater momentum. If the vehicles have the same mass, then they will have the same momentum.
