Collisions

Front

What is a collision?

Back

A collision is an event where two or more objects come into contact with each other, resulting in a transfer of energy and momentum.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as gravitational potential energy based on height.

Front

What is the elastic limit?

Back

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

Front

What is the breaking point?

Back

The breaking point is the point at which a material fails and breaks under stress.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another, affecting motion and energy.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through air, affecting its speed and energy.

Front

How does mass affect acceleration?

Back

According to Newton's second law, greater mass requires more force to achieve the same acceleration as a lower mass.

Front

What happens to objects during a collision?

Back

During a collision, objects may deform, change shape, and transfer energy and momentum to each other.

Front

What is momentum?

Back

Momentum is the product of an object's mass and velocity, represented as p = mv, and is conserved in isolated systems.
