Forces that change Motion.
What is an example of a non-contact force?
One example of a non-contact force is gravity. It is a force that acts between two objects without any physical contact between them. For instance, the gravitational force exerted by the Earth attracts objects towards its center without any direct contact between the Earth and the objects.
An example of a non-contact force is gravity.
To understand non-contact forces, let's first define what a force is. In physics, a force is any influence that causes an object to undergo a change in speed, direction, or shape. Contact forces are forces that occur when two objects physically interact, such as pushing a book or pulling a rope. On the other hand, non-contact forces are forces that act on objects without direct physical contact. An example of a non-contact force is the force of gravity.
Gravity is a force that attracts objects towards each other. It is a non-contact force because it can act on an object even when there is no direct physical contact. For instance, when you drop an object, such as a pencil, it falls to the ground due to the force of gravity. In this case, the Earth's gravitational force is acting on the pencil, causing it to change its motion by accelerating downwards.
Another example of a non-contact force is magnetic force. When you bring two magnets close to each other, you can observe a force of attraction or repulsion between them, even though they are not physically touching. This is a result of the magnetic fields interacting, resulting in a non-contact force.
In both cases, gravity and magnetic force, the objects experience a change in motion without direct physical contact, exemplifying non-contact forces.
