8.1 Contact Forces (Live list)

Front

What is a headwind?

Back

A headwind is wind that blows directly against the direction of travel, making it harder for an object to move forward.

Front

What is potential energy?

Back

Potential energy is the stored energy in a system due to its position or configuration, which can be converted into kinetic energy.

Front

What does deformation mean?

Back

Deformation refers to a change in shape or size of an object due to applied force.

Front

What is the elastic limit?

Back

The elastic limit is the maximum extent to which a material can be stretched without undergoing permanent deformation.

Front

What is a collision?

Back

A collision is an interaction between two objects that make contact with each other, resulting in a transfer of energy and momentum.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact, affecting how easily they can slide past each other.

Front

What is the breaking point?

Back

The breaking point is the maximum stress or force that a material can withstand before it fails or breaks.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air, slowing it down.

Front

What is a tailwind?

Back

A tailwind is wind that blows in the same direction as the movement of an object, helping it to move faster.
