For an object to move, there must be a force. A force is a push or pull that causes an object to move, change direction, change speed, or stop. Not all forces cause motion, however. Some forces, like gravity and friction, resist or work against movement.

Thus, force would cause. acceleration in horizontal motion.

According to Galileo and Newton, when is a force needed to keep an object moving? Only when friction (or some other oppositional force) is present is a force needed to keep an object moving. The net force equals mass times acceleration.

Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).

If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh. We define this to be the gravitational potential energy (PEg) put into (or gained by) the object-Earth system.

Yes, it is possible for motion to exist without force. An application of an external force is required to change the state of the motion. When the force is removed, the object acquires a new constant speed/direction.

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. So forces cause acceleration.

Yes, force can deform a given body.

To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction. If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced.

Forces acting on an object may be balanced or unbalanced. When the forces acting on an object have equal strength and act in opposite directions, they are balanced. Gravity is a force that pulls objects toward one another. For example, Earth pulls all objects toward it.

Examples of balanced forces:

• The weight of an object and the normal force acting on a body are balanced.
• A car that is pushed from opposite sides with equal force.
• A lizard on a wall in a vertical position.
• A ball hanging by a rope.
• A weighing balance where the weight in both of the pans is exactly equal.

Practically anything that moves is a result of the exertion of unbalanced forces on it. If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This is an example of unbalanced force.

Since they are equal and opposite forces, the book does not move. Unbalanced forces exist when there are unequal forces acting upon the object, which leads to a change in the state of motion. Unbalanced forces can lead to a change in direction, a change in speed, or both a change in direction and in speed.

Sinking of an object Sinking of an ship due to unbalanced forces. An object sinks in water due to the unbalance between the upthrust and the gravitational force. Objects float in the water at balanced force conditions.

In science, a force is a push or a pull. All forces have two properties: direction and magnitude.

A force is a push or a pull. When you throw a ball, the force of your throw moves it forwards, the force of gravity pulls it down and the force of air resistance slows it down.

The three types of non-contact forces are gravitational force, magnetic force, electrostatic and nuclear force.

Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

The four fundamental forces, also known as the Universal forces are electromagnetic force, strong nuclear force, weak nuclear force, and gravitation. The strong nuclear force acts over a small distance while gravity acts over a long distance. Scientists have been trying to combine all forces into one.
