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

∙ 12y agoThe speed (or velocity) of any object is defined as distance divided by time. So, you just take the distance it moved and divide it by the time it took to get there. If your object moved 2 miles in 1 hour, its speed would be 2 miles per hour.

∙ 12y agoThe speed of an object can be found by dividing the distance travelled by the object by the time taken for the object to travel that distance.
Speed=Distance/Time

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.
Why is it not possible to use sonar to determine the speed of an object travelling faster than the speed of sound?
Sonar is sound waves bounced off a object so if you are going the speed of sound the waves cannot bounce off the object and determine 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 factors must be known to determine the velocity of an object in motion?
The object's speed and direction.
How do you determine the speed of a moving object?
The average speed of an moving object is determined by using the formula velocity=distance/time or v=d/t.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
What two things must you know to determine speed?
Speed is the rate at which an object moves. To determine the rate at which that object moves, we'll have to look at a given distance that it covered when it moved, and at the time it took to cover that distance. The distance per unit of time is the speed of the object.
What is the equasion used to determine the momentum of an object?
Momentum = (mass) multiplied by (speed)
What two factores determine how much kinetic kinetic an object has?
Its the mass and the speed
If you know the distance an object has travled in a certian amount of time you can determine?
Speed.
Which two factors can be calculated to determine the kinetic. energy of an object?
Mass and Speed
If you know the distance of an object has traveled in a certain amount of time you can determine the?
speed
How does a knife decrease the force or the distance?
Because the size of the objects determine the speed and force of the object, the smaller the object, the higher the speed and the less force is applied whereas a larger object will apply more force and less speed.
