¿Qué es una fuerza?

The video tutorial explores the concept of movement and forces, explaining how forces can alter the state of rest or motion of objects. It delves into the types of forces encountered in daily life, such as gravitational and electromagnetic forces, and how they can be measured using a dynamometer. The tutorial also covers the concept of equilibrium, where forces counteract each other, resulting in static or dynamic balance. The unit of force, the Newton, is introduced, and the idea of a system of forces acting on a body is explained.

What is the primary effect of an external force on an object at rest?

• It decreases the object's size.

• It increases the object's temperature.

• It alters the object's state of rest.

• It changes the object's color.

Which of the following is an example of a force acting at a distance?

• Gravitational pull

• Pushing a door open

• Kicking a ball

• Lifting a box

What device is used to measure the force that deforms bodies?

• Dynamometer

• Barometer

• Speedometer

• Thermometer

In the International System of Units, what is the unit of force?

• Newton

• Watt

• Joule

• Pascal

What happens to a body when the forces acting on it are perfectly balanced?

• It accelerates rapidly.

• It emits light.

• It remains in static or dynamic equilibrium.

• It changes its shape.
