Contact Forces

Front

What is kinetic energy (KE)?

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

How does kinetic energy change with speed?

Back

Kinetic energy increases as speed increases, since it is proportional to the square of the speed.

Front

What occurs during a collision between two objects?

Back

During a collision, energy is transferred between the objects, which can result in changes to their motion and shape.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What happens to solid objects during a collision?

Back

Solid objects may change shape or deform when contact forces are applied during a collision.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is elastic deformation?

Back

Elastic deformation is a temporary change in shape that occurs when a force is applied, and the object returns to its original shape once the force is removed.

Front

What is inelastic deformation?

Back

Inelastic deformation is a permanent change in shape that occurs when a force is applied, and the object does not return to its original shape.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented as p = mv.
