You need the initial and final velocities, and time interval to answer this question.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
The acceleration of a car moving in a circle with uniform speed is directed towards the center of the circle and is called centripetal acceleration. This acceleration is given by the formula a = v^2/r, where v is the speed of the car and r is the radius of the circle.
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
If a car moving in a straight line travels equal distance in equal time no matter how small these distances may be, the car is said to be moving with a CONSTANT or Uniform Velocity.
Well, it depends on the environment, but say we are in the most perfect environment, flat, constant friction, no air resistance, no resistance on the car's internal workings, then yes, but say it was going 30 Km/h, then it would keep accelerating until it reached 30, then it would just keep moving at 30 Km/h
Yes, a body moving with uniform acceleration has momentum. Momentum is the product of an object's mass and its velocity, and acceleration is the rate of change of velocity. As long as the object is moving and has mass, it will have momentum.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
When a car's velocity is uniform, its acceleration is zero. This means that the car is not speeding up or slowing down, but maintaining a constant speed. Uniform velocity indicates that there is no net force acting on the car to change its motion.
Let us suppose that the displacement is given by, x = kt2 , where k is constant of proportionality. Therefore, velocity of the body, v = dx/dt = d(kt2)/dt = 2kt Since, velocity depends on time ,the body is not moving with uniform velocity.... Again, acceleration of the body, a = dv/dt = d(2kt)/dt = 2k As the acceleration is independent of time , the body is moving with uniform acceleration..
Acceleration due to gravity is the constant rate at which an object falls towards the Earth, which is approximately 9.81 m/s^2. Uniform accelerated motion refers to an object moving with a constant acceleration, such as a car increasing its speed by a fixed amount every second.
