What is the eq of constant for a sphere rolling in a frictional less incline surface?
The equation for the constant acceleration of a sphere rolling without slipping on a frictionless inclined plane is given by a = g * sin(theta) / (1 + (I / (m * r^2))), where a is the acceleration, g is the acceleration due to gravity, theta is the angle of the incline, I is the moment of inertia of the sphere, m is the mass of the sphere, and r is the radius of the sphere.

What forces are action forces for a block on an inclined plane?
The forces acting on a block on an inclined plane are the gravitational force pulling the block downhill (parallel to the incline) and the normal force perpendicular to the surface of the incline. Additionally, there may be frictional forces acting on the block depending on the surface of the incline.
What affects the speed of a rolling ball?
The factors that affect the speed of a rolling ball include the force applied to the ball, the incline or surface it is rolling on, the mass and size of the ball, and the presence of friction. A greater force, steeper incline, lighter ball, and lower friction will generally result in a faster rolling speed.
Are you agree that your weight is equivalent to the friction force. Why?
No. On a horizontal surface the normal force is equal to weight. If you are moving at constant velocity you only overcome frictional force, which is not equal to weight. This is easier to see on an incline. At some point an object will slide at constant velocity down the incline. This is related to trig functions of the angle of incline multiplied by the weight which is always less than the weight.
Why does a toy car rolling at constant speed down a straight incline track slow down when reaching the base of the incline?
The toy car slows down at the base of the incline due to friction between the wheels and the surface of the incline. Friction causes a resistance force that acts opposite to the direction of the car’s motion, leading to a decrease in speed. This loss of kinetic energy due to friction is converted into heat, sound, and deformation of the wheels.
What is an example of constant motion?
A ball rolling at a constant speed at the same rate of speed on a still surface.

What is a solid that has 1 flat surface and can roll?
A cone. If your definition of rolling includes the motion of a cone down an incline.

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.
How much work or energy does it take to push a car up an incline?
The answer depends on a number of factors: - the weight of the car - the steepness of the incline - the frictions of the of both the car to the incline surface and the pusher to the incline surface
Does the frictional force depend on the area of surface contact?
No, the frictional force does not depend on the area of surface contact. It is primarily determined by the nature of the surfaces in contact and the normal force pressing the surfaces together. The coefficient of friction between the surfaces also plays a role in determining the magnitude of the frictional force.
What frictional forces are at work?
Frictional forces include static friction (preventing movement), kinetic friction (opposing motion), rolling friction (resistance between rolling surfaces), and fluid friction (resistance in fluids). These forces arise from the interaction between two surfaces in contact and can vary based on factors such as surface roughness and the nature of the materials involved.
What forces make marbles roll?
Marbles roll due to a combination of gravitational force pulling them downward and frictional forces between the marble and the surface it is rolling on. If the surface is smooth, gravity will dominate and the marble will roll faster. If the surface is rough, friction may slow down the marble's rolling.
What is the force stopping from rolling down a hill?
The force stopping an object from rolling down a hill is friction. Friction occurs between the object and the surface of the hill, creating a resistance that opposes the object's motion. It is this frictional force that prevents the object from sliding or rolling down the hill uncontrollably.
