Final answer:
The required force to move an object up an incline depends on the gravitational force component along the plane, mass of the object, and acceleration intended. Calculations include use of the angle of the incline, mass, gravitational constant, and any other necessary acceleration.
Step-by-step explanation:
The force required to move an object up an inclined plane is determined by the component of the gravitational force acting along the plane. If the incline is frictionless and the plane makes an angle θ with the horizontal, this force is given by the formula F = m × g × sin(θ) + m × a, where m is the mass of the object, g is the acceleration due to gravity (9.81 m/s²), and a is the acceleration of the object up the incline. For example, to find the force applied to a 100.0-kg crate on a frictionless incline at 30° for an acceleration of 2.0 m/s² up the plane, we calculate it as F = 100.0 kg × 9.81 m/s² × sin(30°) + 100.0 kg × 2.0 m/s², resulting in a certain force in newtons.
