Forces Recovery

Front

What is the definition of force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is equilibrium in a force system?

Back

Equilibrium occurs when the net force acting on an object is zero, resulting in no acceleration.

Front

What is the net force?

Back

The net force is the vector sum of all the forces acting on an object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the movement.

Front

What are contact forces?

Back

Contact forces are forces that occur when two objects are in physical contact with each other.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts on an object without physical contact, such as gravity or magnetic force.

Front

How does an unbalanced force affect an object?

Back

An unbalanced force causes an object to accelerate in the direction of the larger force.

Front

What is the formula for calculating net force?

Back

Net force = Sum of all forces acting on an object.

Front

What is the role of gravity in force systems?

Back

Gravity is a force that pulls objects toward the center of the Earth, affecting their weight and motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
