Physical Science S1 Final Flashcard

Front

How does weight change when an object is taken to the Moon?

Back

Weight decreases due to lower gravitational pull on the Moon.

Front

What does Newton's 1st Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is an example of energy transformation in a car engine?

Back

Chemical energy is transformed into mechanical energy.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

In circular motion, what direction does the centripetal acceleration point?

Back

Centripetal acceleration points towards the center of the circular path.

Front

What is the definition of force?

Back

A push or pull on an object resulting from its interaction with another object.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = mg).

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion, calculated as KE = 1/2 mv².

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration, often gravitational potential energy.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
