5.2&5.3 Motion, Energy and Force Review

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is thermal energy transfer?

Back

Thermal energy transfer is the process of heat moving from one object to another due to a temperature difference.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is energy at rest.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

What is motion?

Back

Motion is the change in position of an object over time. It is described by its direction and speed.

Front

What are the two main types of energy?

Back

The two main types of energy are kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is the relationship between speed and motion?

Back

Speed is a measure of how fast an object is moving, which is a key characteristic of its motion.

Front

What is the definition of force?

Back

Force is a push or pull on an object that can cause it to change its velocity (speed or direction).

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is net force?

Back

Net force is the total force acting on an object when all the individual forces are combined.
