Speed = Distance ÷ Time
or s = d/t
For example, the speed of a car that traveled 40km in 30 minutes:
s = 40/30 minutes
s = 40/0.5 hours
s = 80km/h
Remember, if the time is given in minutes you must remember to convert this to hours by dividing the time by 60, e.g. 30 mins = 0.5 hours

What determines the terminal velocity of an object?
Gravity and drag. Gravity accelerates the object and drag (caused by friction) slows it down. When the full effect of these two forces have been applied to an object, that object is said to have reached terminal velocity. A combination of mass, the size of the leading surface area and the shape of the object determine it's velocity. Example: A man with a closed parachute falls faster than a man with an open parachute.
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.
How do you know a object's speed and velocity?
Velocity = Delta-x / Delta-t, where x is position, t is time, and "Delta" is the "Change in" operator.Velocity is a vector, so I probably should have written x as x, or x-arrow, or some other notation to indicate it was a vector quantity, but putting an arrow hat on something is a little difficult to do here, and just making it bold is kind of subtle and could be missed.Speed is the magnitude of the velocity vector.
If the speed of an object does not changed then the object is traveling at a?
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
The speed of an object at any instant in time is its?
The speed of an object at any instant in time is its instantaneous speed.
What do the speed and dirction of a moving object determine for that object?
The speed and direction of a moving object determine its velocity. Velocity is a vector quantity that describes both the speed and direction of motion of an object.
What is necessary to determine the speed of an object?
To determine the speed of an object, you need to know the distance the object travels and the time it takes to travel that distance. By dividing the distance by the time, you can calculate the speed of the object.
What measurements are needed to be done to determine the speed of an object?
To determine the speed of an object, you need to measure the distance the object travels and the time it takes to travel that distance. By dividing the distance by the time, you can calculate the speed of the object.
What two pieces do you need to know to determine the speed pf an object?
To determine the speed of an object, you need to know the distance the object travels and the time it takes to travel that distance. By dividing the distance by the time, you can calculate the speed of the object.
Determine if the momentum of an object moving in a circular path at constant speed is constant.?
determine if the momentum of an object moving in a circular path at constant speed is constant.
What two quantities must be known in order to determine the distance to an object?
To determine the distance to an object, you need to know the object's speed and the time it takes for the object to travel to a specific location. By multiplying the speed by the time, you can calculate the distance the object has traveled.
Does speed determine how much ineria an object has?
No, speed alone does not determine how much inertia an object has. Inertia is the resistance of an object to changes in its state of motion, and it depends on the mass of the object. An object with more mass will have more inertia, regardless of its speed.
Why do you need a frame of reference to determine speed of an object?
A frame of reference is needed to determine the speed of an object because speed is a relative measure that depends on the observer's perspective. By having a reference point that is stationary or moving at a known speed, we can compare the object's motion to that reference point and calculate its speed accurately.
Name at least two factors that determine force of impact?
The speed or velocity of the object before impact and the mass of the object are two important factors that determine the force of impact. The greater the speed or mass of the object, the higher the force of impact will be.
What two factors determine the speed of an object?
The speed of an object is determined by both the distance it travels and the time it takes to travel that distance. By dividing distance by time, you can calculate the speed of an object.
If you know the distance of an object has traveled in a certain amount of time you can determine the?
speed of the object by dividing the distance traveled by the time taken. Speed is a measure of how fast an object is moving.
What two factors must be known to determine the velocity of an object in motion?
The object's speed and direction.
