Can an object have constant speed and constant acceleration?
Hence, a body can have a constant speed and still be accelerating. Note: All circular motions where the object is moving with constant velocity are a great example of cases where the body will have constant speed but it will be still accelerating since the velocity changes due to a change in direction of the object.
Is it possible for an object to move with constant speed but the direction at each point can be changed during its motion?
Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.
How is it possible for an object to have speed but not velocity?
An object following a circular path can be covering the same distance along the circle’s circumference with every passing minute, giving it a constant speed. Since a change in either speed OR direction means a change in velocity, the object’s velocity is not constant.
Is it possible for an object to accelerate and still travel in a straight line?
It is never possible for an object to accelarate at a constant velocity because change in velocity is required for accelaration.
Can you move with constant velocity but not constant speed?
No, it doesn’t. Velocity is a vectorial quantity, it has magnitude (speed) and direction. Even though the speed is constant in this particular example, the direction changes all the time.
Is it possible for an object to have constant velocity but not constant speed if so give an example if not explain why not?
Yes it is possible to have a constant speed but a varying velocity in case the objects changes its direction. Constant velocity and change in speed is not possible as with the change in speed velocity will change. Velocity is a speed of the object with specification of its direction.
Is it possible for an object to have motion in the absence of forces on the object?
Yes, it is possible to have motion without a force being present. Newton’s first law states that, in fact, an object must continue to move at the same…
What would be the acceleration of an object moving in a straight line at constant speed?
If the acceleration is 0, the object shouldn’t have any external forces applied on it. Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time.
Why can an object accelerate while Travelling at a constant speed but not at constant velocity?
An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. If an object’s velocity is constant, however, its acceleration will be zero. Since it travels in a straight line, its direction does not change.
How do you find constant acceleration?
For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, then its constant acceleration is 3 m/s2….Solution
- Use the first equation of motion, v=u+at.
- Use the first equation of motion again, with u=30 and v=80: 80=30+52t.
