What did Galileo discover about the amount of speed a ball gained each second when rolling down an inclined plane?
Galileo discovered that the speed gained by a ball rolling down an inclined plane is constant and increases linearly with time. This led to the development of the concept of acceleration, where an object's speed changes at a constant rate over time.
Is there a relationship between the mas of a moving ball and its speed while rolling down an inclined plane?
Mass does not affect the acceleration of an object due to gravity. Any object of any size or mass will fall at the same speed. A ball rolling down an inclined plane is accelerated by gravity, so its speed won't be affected by its mass at all.
Galileo imagined rolling a ball down a fixed and then back up ramps of varying steepness?
Galileo's experiment with rolling a ball allowed him to observe how the height of a ramp affected the speed of the ball. By varying the steepness of the ramps, he could understand how gravity influenced the motion of the ball. This experiment helped him develop his theories on motion and gravity.
Are The molecules of the liquid inside a thermometer increase in speed when the thermometer is cooled.?
No, the molecules of the liquid inside a thermometer do not increase in speed when the thermometer is cooled. Instead, they lose energy and slow down, causing the liquid to contract and move down the scale. When the thermometer is heated, the molecules gain energy and speed up, leading to expansion of the liquid.
When a 5.0 kg bowling ball is rolling down the lane at 4.0 milliseconds . What is the kinetic energy of the bowling ball?
From the information provided it is impossible to answer the question. You require the velocity or speed of the ball and that is not measured in milliseconds - which a measure of time!
What happens to the velocity of a ball that is rolling down a hill?
The velocity of a ball rolling down a hill will increase due to the acceleration caused by the pull of gravity. As the ball gains speed, its velocity will continue to increase until it reaches the bottom of the hill.
If a ball rolls down a hill does its speed or acceleration increase?
The speed of the ball increases as it rolls down the hill due to the acceleration caused by gravity. The ball will accelerate at a constant rate as it moves downhill, increasing its speed until it reaches the bottom of the hill.
Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?
The speed of the ball is greatest when it is thrown upward and decreases as it reaches the peak of its trajectory. The speed continues to decrease as the ball falls back down due to the force of gravity pulling it towards the ground.
Toss a ball upward what is the change in speed each second on the way up and on the way down?
The change in speed each second when the ball is tossed upward will decrease by 9.8 m/s each second due to gravity until it reaches its highest point and starts falling back down. On the way down, the speed will increase by 9.8 m/s each second as gravity accelerates the ball towards the ground.
Why does the speed of the ball thrown up decrease?
The speed of a ball thrown up decreases because of gravity acting against the initial velocity. As the ball goes up, gravity pulls it back down, causing its speed to decrease until it reaches its peak height and momentarily stops before falling back down.
As the speed of a rolling ball is increasing,the increasing speed is accompanied by?
momentum As the speed of a rolling ball is increasing, the increasing speed is accompanied by: a. increasing momentum.
Does reactive bowling ball increase ball speed?
No. The highest ball speed you can register is the moment it leaves your hand. After that moment friction slows the ball down. Generally if a bowling alley has speed sensors at the pin deck the register speed is about 1.5mph slower than when the ball left your hand. Being that reactive resin has a higher coefficient of drag against the lane it will slow your ball down more than if our threw a plastic house ball in similar shape.
What happens to the speed of a ball when it is thrown upwards in the air?
The speed of the ball decreases as it moves against gravity and eventually reaches 0 at its highest point before falling back down.
If you throw a ball straight upward at a speed of 20 meters per second how long will it take to reach zero speed?
The ball will reach zero speed at the peak of its trajectory after approximately 2 seconds. This is because the acceleration due to gravity will gradually slow down the ball until it stops momentarily before falling back down.
A ball is thrown upward and caught when it comes back down In the presence of air resistance the speed with which it is caught is?
Slower than the initial speed it was thrown upward with due to air resistance causing the ball to lose speed as it travels through the air. The force of air resistance acts against the direction of motion and slows down the ball.
How do you slow down a ball?
To slow down a ball, you can apply friction by rubbing it against a surface, increase air resistance by opening a parachute or adding drag-inducing features, or employ a magnetic field to create resistance. Each method can help reduce the speed and velocity of the ball effectively.
When a ball rolls down an inclined plane it gains speed because of gravity?
Yes, as the ball moves down the incline, gravity pulls it toward the center of the Earth, causing it to accelerate. The force of gravity acting on the ball gives it kinetic energy, resulting in an increase in speed as it moves downhill.
