A ball striking a wall in which the force of the ball on the wall is equal to the force of the wall on the ball. will it accelerate?
Acceleration is the change in speed or direction. When the ball strikes a wall it will likely rebound. That is a change in direction. Some of the energy of the ball went into heat and sound so, that is also a change in speed. The only wall that would have no effect on the ball's acceleration would be a wall of light or an imaginary wall.
Why scocer is physically demanding sport?
It involves running, often at high speed with frequent direction changes and kicking the ball.
What happens to the direction of motion of the ball what changes it direction of motion?
A force acting on the ball, at an angle to its line of motion, will cause its direction of motion to change.
Picture a ball traveling at a constant speed around the inside of a circular structure Is the ball accelerating?
As the ball moves in a circular path, it changes it's direction every moment. velocity is a vector and it depends both on speed and its direction. So, as the ball is changing its direction every time, we can say that it is changing its velocity as well. So, the ball is actually accelarating
Will governor fly ball sense turbine speed changes?
Yes, governor fly ball can sense the Turbine speed changes. The mechanical governor is based on this fly ball mechanism.
What is an example of constant speed with changing velocity?
Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.
Why are the speed and direction of a ball changed when a batter hits the ball?
It's basic physics and depends on the speed of the swing, the mass of the bat,(kinetic energy) and the angle at which the ball was hit. The direction the ball travels largely depends on whether the swing was early or late (angle change) but you must also consider ball rotation, wind speed (and the occasional pigeon..lol) Simply put lets say the ball was thrown at a tremendous speed and therefore had more kinetic energy then your swing. It would then be you and your bat changing speed and direction instead of the ball.
Explain how momentum is conserved when a ball bounces against a floor?
The ball's momentum changes in one direction, the momentum of planet Earth in the opposite direction.
What are the changes produced by force?
Force can produce several changes. It can change the shape or position of an object by causing it to move or deform. It can also change the speed or direction of an object's motion. Additionally, force can produce changes in the motion of fluids, such as causing them to flow or change direction.
Can an object have a varying speed it its velocity is constant?
Of course, since velocity is a vector quantity and speed is a scalar quantity, velocity has something speed does not: direction. Thus, an object can travel at the same speed by has a changing direction of movement, and therefore a changing velocity. For instance, a ball on a string moving in a circle at the same speed is constantly changing its velocity, which results in its path of motion.Yes. Velocity is (speed and direction of motion). If direction changes, then velocitychanges, even if speed is constant.Examples:-- Car going around a curve at a constant speed has changing velocity.-- Anything traveling a circular path at a constant speed has changing velocity.
In what ways is a bouncing ball accelerating?
-- On the way down, its speed is increasing, which is a change in velocity, i.e. an acceleration. -- At the bounce, its direction changes, which is a change in velocity, i.e. an acceleration. -- On the way up, its speed is decreasing, which is a change in velocity, i.e. an acceleration.
What kind of friction does a ball meet when it is thrown?
When a ball is thrown into the air, it encounters drag. Drag is the opposing force acting in the opposite direction of the ball. Drag slows down the ball's speed.
