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.
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.
Who discovered the acceleration?
The concept of acceleration was first described by Galileo Galilei in the 17th century. He conducted experiments with rolling balls and inclined planes to study how the speed of an object changes over time. He formulated the equation for acceleration as a = Δv/Δt, where a is acceleration, Δv is change in velocity, and Δt is change in time.
What is a area of flat or rolling land at a high elevation called?
Plateau
Which is easier to stop sliding or rolling friction?
== == AnswersIt is easier to stop sliding friction than rolling friction. The force due to sliding friction will always be greater than the force due to rolling friction. And since friction force will be in the opposite direction of motion it will be easier to stop an object in motion that is sliding than one that is rolling.
What is the effect of different surfaces types on the rolling distance of a ball?
Different surface types can affect the rolling distance of a ball by changing the amount of friction between the ball and the surface. Surfaces with higher friction, like rough surfaces, tend to reduce the rolling distance of a ball, whereas smoother surfaces reduce friction and allow the ball to roll further. In general, smoother surfaces will result in longer rolling distances compared to rougher surfaces.
What is the Speed of a ball rolling on different surfaces?
The speed of a ball rolling on different surfaces can vary depending on factors such as friction, surface roughness, and incline. Generally, a ball will roll faster on smoother surfaces with less friction compared to rougher surfaces with more friction. Incline can also affect the speed of a rolling ball, as gravity will play a role in accelerating or decelerating the ball.
What are disadvantages for rolling friction?
Rolling friction can create heat and wear on the surfaces in contact, leading to energy loss and decreased efficiency. It can also vary with different surfaces and conditions, making it difficult to predict accurately.
What is disadvantages for rolling friction?
Rolling friction can cause energy loss due to the deformation of surfaces in contact, leading to reduced efficiency. Additionally, rolling friction can cause wear and tear on the surfaces in contact, requiring maintenance and replacement.
What are different ways of decreasing friction?
Making surfaces smooth and hard Rolling instead of sliding (roller bearings instead of sleeve bearings) Lubrication

What are Different between static friction and sliding friction and rolling friction?
Friction is a force between to surfaces that resists motion. Static friction is the resistance to motion when two surfaces are not moving relative to each other. Sliding friction is the resistance to motion when two surface are sliding, one over the other. Sliding friction is less than static friction for the same two surfaces. For rolling friction an object is rolling, like a tire on a road. It's what provides traction between the two and makes the car "go." For a tire on a road, rolling friction is less than sliding friction.
What do the different forms of friction have in common?
Different forms of friction, such as static, kinetic, and rolling friction, all involve resistance to motion when two surfaces are in contact. They are caused by microscopic irregularities on the surfaces that interact and oppose relative motion. In all cases, friction converts mechanical energy into heat.
What kind of friction occurs when solid surfaces slide over each other?
The type of friction that occurs when solid surfaces slide over each other is called kinetic friction. This type of friction opposes the motion of the objects and is influenced by factors such as the smoothness of the surfaces and the force pressing the surfaces together.
What is a good subject for an investigatory project in physics about displacement and distance?
A good subject for an investigatory project in physics about displacement and distance could be examining how different surfaces affect the distance traveled by a rolling object. This project could involve measuring the displacement and distance covered by a rolling ball on surfaces with varying friction levels.
What type of friction is used as a lubricant and replaces sliding friction to motor oils?
Rolling friction is used as a lubricant in place of sliding friction in motor oils. Rolling friction occurs when two surfaces move against each other with rolling motion, reducing friction and wear on the surfaces.
Does the texture of what something is rolling on affect its speed?
Yes, the texture of what something is rolling on can affect its speed. Rough surfaces create more friction, slowing down the object. Smooth surfaces have less friction, allowing the object to roll faster.
