Force Test

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.

Unbalanced forces occur when two forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Gravity is the force that attracts two bodies towards each other, pulling objects towards the center of the Earth.

Tension force is the pulling force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Compression force is a force that acts to compress or shorten an object, pushing its particles closer together.

Shear force is a force that causes parts of a material to slide past one another in opposite directions.

Torsion force is a twisting force that causes rotation around an axis.

Air resistance is a type of frictional force that opposes the motion of an object through the air.

Friction opposes the motion of the cart as it moves down the ramp, acting against the force of gravity.
