What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object, showing all the forces as arrows pointing in the direction they act.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface, acting perpendicular to the surface.

Front

What is weight force?

Back

Weight force is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).

Front

What is frictional force?

Back

Frictional force is the force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is thrust?

Back

Thrust is the force that propels an object forward, often produced by engines or propellers.

Front

What is buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on an object immersed in it, counteracting the object's weight.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their directions (F_net = F1 + F2 + ...).

Front

What happens when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.
