A ball is travelling with uniform translatory motion . This means that

Options

A. it is at rest
B. he path can be a straight line or circular and the ball travels with uniform speed.
C. all parts of the ball have the same velocity (magnitude and direction) and the velocity is constant
D. the centre of the ball moves with constant velocity and the ball spins about its centre uniformly.

Explanation

To solve the question regarding the ball traveling with uniform translatory motion, we can break it down into several key points:

### Step-by-Step Solution:

1. **Definition of Uniform Translatory Motion**:
- Uniform translatory motion refers to the motion of an object where all points of the object move with the same speed and in the same direction.

2. **Constant Velocity**:
- In uniform translatory motion, the velocity of the object remains constant. This means that both the magnitude (speed) and direction of the velocity do not change over time.

3. **Uniform Speed**:
- The ball is traveling with uniform speed, which means that it covers equal distances in equal intervals of time, regardless of the duration of the time intervals.

4. **Same Velocity for All Parts**:
- All parts of the ball have the same velocity. This means that every point on the ball is moving at the same speed and in the same direction.

5. **Path of Motion**:
- The path of the ball can be either a straight line or a circular path. However, in both cases, the key characteristic of uniform translatory motion is that the speed and direction remain constant.

6. **Conclusion**:
- Therefore, we conclude that in uniform translatory motion, the ball travels with constant velocity, all parts of the ball have the same velocity, and the motion can occur along a straight or circular path.

### Final Answer:
A ball is traveling with uniform translatory motion means that it has constant velocity, all parts of the ball have the same speed and direction, and the motion can be along a straight line or circular path.
