A the moment when the ball just touches the thrower's hand, it will have the velocity with which it was thrown and the acceleration will be equal to the acceleration due to gravity at the place acting vertically downwards.
A body moving with uniform velocity is in equilibrium when it moves with uniform velocity as no acceleration i.e. no net force acts on the body.The sum of all forces must be zero in this case. (To avoid rotation, the sum of all torques must also be zero).
When we ride on a motor cycle we turn the throttle and the bike's speed goes on increasing. This is positive acceleration. Now we switch off the motor. The bike comes to rest after travelling some distance. This is due to negative acceleration due to frictional force between the tyre and the floor. In this case acceleration is in opposite direction to the direction of motion of the bike. Hence acceleration becomes a vector.
Remember that velocity is a vector quantity which means it needs two criteria to be defined; a magnitude, and a direction. When we discuss the magnitude of velocity, what we are talking about is the speed (30m/s, 45mph, etc). Those examples are examples of speed; it is only when we add a direction that it becomes 'velocity'. So, the difference is: "25m/s" is a speed, but "25m/s east" is a velocity. Speed (the magnitude of velocity) is calculated by taking the total displacement divided by the total time. Speed=(distance travelled)/(time it takes). Hope this helps
When a body is thrown from a certain height, it experiences projectile motion where it follows a curved path due to the combination of its initial velocity and the force of gravity. As the body moves through the air, it accelerates downwards due to gravity but continues moving horizontally at a constant velocity unless acted upon by external forces. The body eventually reaches a peak height where its vertical velocity becomes zero before falling back down to the ground.
The conclusion of a projectile motion experiment typically involves summarizing the key findings related to the trajectory, velocity, angle of projection, and range of the projectile. It may also discuss any sources of error in the experiment and suggest ways to improve accuracy in future investigations. Ultimately, the conclusion should tie back to the experiment's purpose and whether the results support or refute the initial hypothesis.

Gabriele Reinsch of East Germany set the current discuss throwing world record of 251 ft. 11.6 in. in 1988.
Extrapolate the experimental values of acceleration, vs. angle of the incline, to find the acceleration when the angle of inclination = 90 degrees. The acceleration at 90 degrees will equal 9.81 m/s/s, since this is the free-fall acceleration.

Scroll down to related links and look at "Speed of sound - Wikipedia". There is a table of the effects of the temperature on sound. Don't say "velocity of sound", call it "speed of sound".
Yes; if the direction changes (for instance, if an object moves in a circle), even if its speed doesn't change, its velocity changes. This is because the term "velocity" also includes the direction.
A discus is a round disc, like a frisbee but without a lip going around the edge. You throw it by spinning yourself and then using your arm to increase the momentum so you get maximum distance.
