How does incline affect speed?
Incline affects speed by causing it to increase or decrease. For example, if something is traveling up the incline, its speed will decrease. If something is traveling down the incline, its speed will generally increase.
How did changing the slope of the incline change your velocity and acceleration values?
changing the slope of the inclined plane changes the values for velocity because of the unbalanced external force exerted on the object increases the velocity.
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.
How does an incline plane reduce amount of input force needed?
by increasing distance over which the force is applied

What causes speed to increase or decrease?
Presence of friction, incline and so on.
Is it better for burning calories to buy a treadmill that has an incline feature?
Yes, you can increase the calories you burn by purchasing a treadmill with an incline feature. Make sure to warm up slowly and to increase the incline small amounts at a time. Keeping the shoulder over the hips and the hips over the ankles.

Does the length of an inclined plane affect final velocity. If the planes are different lengths but all the same height and ending at the same point?
(ignoring friction)yes, it does, the rate of acceleration is tied to the incline angle, so assuming the incline angle remains the same, lengthening the incline will result in a higher terminal velocity. v^2 = (u^2) + (2*a*s)if a mass falls the same vertical distance from rest, regardless of incline angle, its terminal velocity will be the same, converting potential energy (m*g*h), into kinetic energy (0.5m*v^2)
Increasing the length of an incline decrease the energy used?
If you mean using a longer incline to reach the same height, the answer is no. Energy is the ability to do work. Work = Force x distsance. A longer incline will require less force, but since the distance is greater the total energy stays the same.

A 3.70 kg block starts from rest at the top of a 30.0 degree incline and slides 2 m down the incline in 1.50 s Find the acceleration of the block?
A 2 kg block slides down a rough incline with a constant velocity. The angle of incline is θ=30⁰. Coefficient of friction of the incline is, μk=0.5. A horizontal force, F, is acting on the block as shown in the figure. (Assume g=10 m/s and do not forget that the direction is downward!!) (Note: You don’t have to use unit vectors. Mentioning the sign convention correctly for all forces is enough for the answer.) a) Determine the magnitude of the force F. b) Determine the normal force exerted by the incline surface to the block
Will a treadmill workout increase may stamina?
Treadmill workouts are good low impact workouts that can definitely increase stamina, especially if the treadmill has the ability to alter incline and speed.
