According to Education.com, the pull of gravity acts more on an object rolling down a ramp inclined at a steeper angle, hence causing it to accelerate and move faster. For Dummies explains that when objects are rolling down an inclined plane such as a ramp, a component of the force of gravity causes it to accelerate downward.Continue Reading
When the ramp inclines toward the direction of the pull of gravity, an object on the ramp rolls at an acceleration that nears the full force, according to For Dummies. Any object on or near the surface of the earth experiences a constant pull of gravity that is directed straight down. When the object is on a ramp, it does not experience the full straight-down pull of gravity. As Education.com explains, experiments on a ramp do not measure acceleration of gravity, which is typically measured as 9.81 m/s^2.
As The Physics Classroom explains, a tilted surface is defined as an inclined plane in physics. An object on it naturally rolls downward, with its speed being affected by the degree of tilt. An object on a more tilted surface rolls down it at a faster rate.
According to For Dummies, at the point where the ramp is most tilted towards the direction of gravity, the greatest pull of the force acts on it.Learn more about Motion & Mechanics
The angle of pull is used to describe the angle of any muscle and the bone to which it's attached. Orthopedists and physical therapists use this term.Full Answer >
The two main concepts to understand in order to solve projectile motion problems are that projectiles in flight constantly accelerate downward due to gravity and that projectiles fired at an angle have their velocities separated into horizontal and vertical components, which are used to derive different information. Using the numbers from the specific problem, one can use the formulas for these concepts to solve for the answer.Full Answer >
A pulley works by changing the direction that force must be applied to lift an object against gravity. Other, more complex, systems use multiple pulleys to reduce the amount of force that must be applied.Full Answer >
Gravitational potential energy depends on the mass of the object, acceleration because of gravity and the height of the object from a zero position, which is typically the ground or surface where the object is resting. This is because potential energy is the amount of energy stored in an object due to its position and represents the potential for a force, such as gravity, to do work on the object.Full Answer >
