What are the four types of forces?

• centripetal force, centrifugal force, frictional force, and tension force

• magnetic force, electric force, thermal force, and chemical force

• kinetic force, potential force, mechanical force, and thermal force

• gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force

What is tension force?

• Force transmitted through a flexible connector

• Force exerted by a stationary object

• Force that causes an object to move in a circular path

• Force that acts on an object in a fluid

What is compression force?

• The force that acts on an object to stretch it.

• The force that acts on an object to rotate it.

• The force that acts on an object to heat it up.

• The force that acts on an object to compress or squeeze it.

What is shear force?

• Force acting perpendicular to a surface causing deformation or sliding

• Force acting away from a surface causing deformation or sliding

• Force acting at an angle to a surface causing deformation or sliding

• Force acting parallel to a surface causing deformation or sliding

What is bending force?

• The force applied to an object that causes it to rotate.

• The force applied to an object that causes it to stretch.

• The force applied to an object that causes it to break.

• The force applied to an object that causes it to bend or deform.

How do you calculate the force exerted by an object?

• force = mass / acceleration

• force = mass + acceleration

• force = mass - acceleration

• force = mass x acceleration

What are some common applications of forces in everyday life?

• Walking, running, swimming, jumping

• Eating, sleeping, talking, reading

• Cooking, cleaning, gardening, painting

• Pushing, pulling, throwing, lifting, propelling

What is stress in the context of forces?

• Internal resistance or reaction of a material to external forces or loads

• The temperature of an object

• The speed at which an object moves

• The force applied to an object
