What is accelleration?
Acceleration is a change in velocity.
If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
Can you go around a curve with constant velocity?
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
What is accelleration?
Acceleration is a change in velocity.
Is acceleration constant or does it change?
Going back to the equation F=m·a you can see that if the force changes but the mass does not, accelleration will change as well. If mass and force do not change, accelleration will be constant.
How do you compute the formula of acceleration?
a=v-u/t accelleration is velocity minus uniform velocity divided by time
What would have to be true for the velocity to be constant?
the speed would have to change.
What does the slope of they curve on a velocity-versus-time graph represent?
The rate of change in accelleration.
Why is the velocity 0 when your speed is constant?
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.
What is the difference between pound-mass and pound-force?
Local accelleration or gravitation creates force. Mass remains constant despite presence or absence of accelleration or gravity.
When can you have no acceleration?
To make acceleration equal zero. The velocity must be constant. For example, if velocity is constant at 10 m/s^2 its acceleration is zero. The same is true if velocity is 0 m/s^2.
What is the formula for calculating the distance from the initial speed?
When you say initial speed I assume there will be accelleration. If so you could you: s = ut + 1/2at^2. or s = 1/2(u + v)t where s is distance in meters u is initial velocity in ms v is the final velocity in ms a is accelleration in ms^-2 t is time in s If there is no accelleration then s = ut
Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
If an object has zero acceleration what two things could be true about its velocity?
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
