Which of the following is an example of a force that acts at a distance?
Levart [38]

Answer:

3. a leaf falling off of a tree to the ground.

Explanation:

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

F = ma

Where;

  • F represents force measured in Newton.
  • m represents the mass of an object measured in kilograms.
  • a represents acceleration measured in meters per seconds square.

Force can be categorized into two (2) main types; forces that at a distance and forces the act by direct contact with the body.

A force that acts at a distance refers to the force exerted on a body or an object without any physical contact between them such as gravitational force, magnetic force and electric force. This simply means that, there can be a push or pull between objects even when they are not in physical contact with each other due to gravitational, magnetic or electric forces.

<em>Some example of a force that acts at a distance is a leaf falling off of a tree to the ground, a magnet pulling an object to itself, a magnet pushing or repelling another magnet etc. </em>
