Answer 1 - This is because of friction.

Answer 2- This is because the force you exert must be in the same direction as the objects motion. So the part pulling forward does work, when the force pulling upward does not.

How is forced defined?

Force is typically defined as a push or pull that causes an object to move, change its speed, or change its direction. It is described by its magnitude (strength) and direction, and can be exerted through direct contact or through fields such as gravitational or electromagnetic forces.


What can change Earth's surface as a result of the force of gravity is it wind ice landslides or plant root?

Gravity is the driving force behind:- wind (convection currents can only happen in a gravity field) ice (Ice moves and erodes under the pull of the force of gravity) Landslides (here the motive power is the pull of gravity)


How do you do a pull test?

A pull test involves applying force to a component or material to assess its tensile strength. This is typically done by attaching a calibrated force gauge to the material and steadily increasing the force until the material fails. The maximum force at which failure occurs is then recorded as the pull test result.


What are the units of gravitational pull?

Acceleration of gravity is equal to negative 9.8 metres per second squared.The so-called "pull" of gravity is a force. The only difference between the 'pull'of gravity and the 'pull' of a rope is the direction. They're both forces.Here are some widely used units of force:-- newton-- pound-- ton-- stone-- ounce


What is an example of a pull in newton's laws of motion?

An example of a pull in Newton's laws of motion is when you use a string to pull a box across the floor. The tension in the string creates a force in the direction of the pull, causing the box to accelerate according to Newton's second law (F=ma).

Energy in the form of a push or pull?

Energy can be transferred to material things by pushing or pulling AND moving it through a distance. The push or pull is a force, and the amount of energy is the magnitude of the force multiplied by the distance through which it acts. No matter how hard you push or pull, if your force doesn't move through any distance, then no energy is transferred to the thing you're pushing or pulling.

Is force a push or a pull?

Force can be either a push or a pull. When you push a door open or pull a rope, you are applying a force in that direction.


What is the only force affecting an object in gravity that objects is in?

Freefall this means the objects is falling through the air while gravity is pulling.
