Unit 2 Review (Energy, Force, & Motion)

Front

What is mass?

Back

Mass is the amount of matter in an object, which remains constant regardless of its location.

Front

What is weight?

Back

Weight is the force exerted on an object due to gravity, which can change depending on the object's location (e.g., on the Moon vs. Earth).

Front

What happens to energy when an object moves up and down a ramp?

Back

The energy transforms into other forms, such as heat due to friction, leading to a decrease in total mechanical energy.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What does it mean for forces to be balanced?

Back

When forces are balanced, the net force acting on an object is zero, resulting in no change in motion.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

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

Front

How does friction affect motion?

Back

Friction opposes motion, converting kinetic energy into heat and slowing down moving objects.

Front

What is the relationship between speed and distance?

Back

Speed is the distance traveled per unit of time; higher speed means covering more distance in less time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
