To determine if the graph indicates that the ball decelerated, we need to look for a decrease in the ball's velocity over time. If the graph shows a downward trend or a slope that is decreasing, it suggests deceleration. Additionally, if the slope of the graph becomes less steep, it also indicates that the ball is slowing down. Without the visual context of the graph, it's not possible to give a definitive answer.
The motion of the ball between 20 m and 80 m on the graph likely shows a steady increase in distance over time, indicating a consistent speed or acceleration. If the graph is linear, the ball is moving at a constant speed. If the graph is curved, it may suggest that the ball is accelerating or decelerating during that segment of its motion. Overall, the specific characteristics of the motion depend on the slope and shape of the graph in that range.
The displacement, along the direction of measurement, is zero. It need not mean that the object is back at the starting point. The displacement-time graph, measuring the vertical displacement of a ball thrown at an angle, will have displacement = 0 when the ball returns to ground level but, unless you are extremely feeble, the ball will be some distance away, not at its starting point which is where you are. The use of such a graph is not unusual in the elementary projectile motion under gravity.
The heat cause the air inside the ball to expand and undent the ball
i dont knoe
The acceleration of the ball can be estimated by calculating the slope of the velocity versus time graph. If the graph is a straight line, the slope represents the acceleration. The steeper the slope, the greater the acceleration. If the graph is curved, the instantaneous acceleration can be estimated by finding the slope of the tangent line at a specific point on the curve.
look like a ball
If you want the graph to show the acceleration of the ball against time, then the graph is a horizontal line. If you want the graph to show the velocity of the ball against time, then the graph is a straight line sloping downward. If you want the graph to show the height of the ball against time, then the graph is a parabola that opens downward.
The graph will be a straight graph if you plot r2 against v. If we calculate the gradient of the line this is giving us the value of the constant "k" from the equation: k = v r2 With this calculated value of "k" we can calculate the value of the viscosity of the liquid using: Viscosity = 2(Denisity of sphere - Denisty of Glycerol) g 9k
In the traditional scoring system, a dot was used to indicate a ball whereby no run has been scored.
because the ball is a solid object.

The stick to hit the ball in Snooker/Billiards
a beach ball may birst as the air pressure in it will expand.that is how a beach ball will birst.
