When an object speeds up, slows down, or changes direction, it is changing it's velocity, also known as accelerating.
This is a common term in mechanical physics. The formula for velocity is D(distance) / T(time) whereas acceleration is the change in velocity which takes time to do making its fomula: D/T^2

A force can cause an object to change its speed and or direction?
A force can cause an object to change its speed or direction. A force causes acceleration, as given by Newton's equation F=ma, where f is force, m is mass, and a is acceleration. Acceleration occurs when something either changes direction, like a tether ball is accelerating when it goes around the pole, or when the objects speeds up or slows down.Forces give energy to the object it is acting on.The more mass an object has, the harder it is to move, stop, or change the speed or direction of the object.An object will not start moving unless a force acts on it.An object will not stop moving unless a force acts on it.An object will not change speed unless a force acts on it.An object will not change direction unless a force acts on it.unbalanced
Do all transparent objects or substances bend light the same amount?
No. The amount that a particular medium bends light is related to the speed of light within that medium, not its transparency. The medium that light travels through affects the light's speed, and the greater the reduction of speed, the greater the angular distortion. For example, light travels faster through normal air than through glass or water, so when light hits a sheet of glass or a water droplet at an angle, it slows down and changes direction; when it hits the other side of the glass or water droplet and goes back into air it speeds up and changes direction again. if the two sides are perfectly parallel the light travels on in the same direction, but if they are not (as in a prism or a round water droplet), the light can continue on in a different direction. in fact, different wavelengths of light are deflected different amounts by entry into or exit from a given medium, which is what produces spectrums from prisms and rainbows from suspended water droplets. You can test this in a pool, pond, or bathtub: notice how when you look straight down into the water things are not very distorted (though they appear to be a little closer than you'd expect), but when you bend down and look into the water at an angle, objects that are straight look like they have a distinct bend in them.
What is a hole formed when two objects in space collide?
If two objects in space collide the result depends on both relative sizes and speeds of the objects.if the objects are moving with little difference in speed, they will simply stick togetherif the objects are of similar size and moving at high speed, they with both shatter into smaller piecesif the objects are of much different size and moving at high speeds, the smaller one will punch a hole in the larger one called a craterwhen an object about the size of Mars collided with the early Earth shortly after the Earth first developed a solid crust, both objects completely remelted and a spray of mixed Earth's mantle and the object entered orbit about the Earth and when it solidified became the Moon, no crater was left on Earth as it melted completely then resolidified tooetc.
What types of change in motion causes acceleration?
Motion is the change of position over time. The rate of change of position is called or speed. Speed combined with its direction is called velocity. The rate of change of velocity is called acceleration. So, motion in which the speed or direction are changing is accelerated motion. The question uses the word cause, which may be confusing. Technically when a force is applied to a mass, there is acceleration. When there is acceleration the velocity changes. If the object was in motion to begin with, it would speed up or slow down or change direction. If the object was at rest, the force would have caused an increase in speed from zero, so it would start moving. Therefore if you think of a causal relationship, it would be more proper to say force causes acceleration, which IS a change in motion. For an example, an easy one is your bicycle. If you pedal, you are applying force. That force cause the bicycle's speed to increase ... acceleration ... and you are in motion. If you apply more force, you will go faster. If you apply the brakes, you will slow down which is also acceleration (because speed is changing). There is only one way to have motion without acceleration and that is to travel at a constant velocity ... constant speed in a straight line. In practice, there is no motion without acceleration for any period of time, because there is always some minute change in speed or direction.
What is an example of uniformity?
the motion of a vehicle moving at different speeds or turning, or simply those moving objects who are accelerating (changing speed or direction), like falling stone, a car travels in a road where there are curves, an elevator (going up and down), a ferris wheel etc. "non-uniform" motion means "accelerated" motion
How does an object accelerate?
it changes direction,it speeds up or slows down
What happens when a moving object speeds up slows down or changes directions is it acelleration?
what happens when a moving object speeds up,slows down,or changes direction?
When a wave changes direction as it speeds up or slows down its called what?
That is called refraction.
What is the rate of change of velocity which occurs if an object speeds up changes direction or slows down?
Any change in velocity, whether to speed up, slow down, or just change direction, results from acceleration. Acceleration is an expression of the rate of change of velocity.
Which direction is each planet?
All the planets are in motion about the sun. Each at different speeds and distances. The direction to each planet therefore changes over time.
What describes the refraction of a wave?
It means that the wave changes direction when it changes over from one medium to another. This is related to the different speeds the wave has in the different media.
What are the changes produced by force?
Force can produce several changes. It can change the shape or position of an object by causing it to move or deform. It can also change the speed or direction of an object's motion. Additionally, force can produce changes in the motion of fluids, such as causing them to flow or change direction.
How do two objects moving at the same speed have different velocities?
Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction. If two objects move in different directions, their velocities will be different, even if their speeds are the same.Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction.

Rate at which speed or direction changes?
acceleration because of the speeds or diection changes and what is it doing accelerating right if u dont think this then dont beleive me Luvv,, Christy ♥ Lynn♥ DiNatale♥
What 2 things change when an unbalanced force is applied to an object?
When the forces on an object are unbalanced the changes that could happen are the object speeds up, or slows down. And it can changes direction.
What is the definition of non uniform motion in physics?
During uniform motion, velocity is constant, so there is zero acceleration. Non-uniform motion involves a change in velocity, which means there is acceleration. Accelaration is a change in velocity. A change in velocity occurs when a body slows down, speeds up, or turns (changes direction), or a combination of these.
What infromation can you get from a weather map?
