Physical Science Final Exam Review - Physics

Front

What is the definition of force in physics?

Back

A force is a push or pull acting upon an object as a result of its interaction with another object.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

How is potential energy calculated?

Back

Potential energy (PE) is calculated using the formula PE = mgh, where m is mass (in kg), g is acceleration due to gravity (9.81 m/s²), and h is height (in meters).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the relationship between speed, distance, and time?

Back

Speed is calculated as distance divided by time (Speed = Distance / Time).

Front

What is the formula for calculating average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the significance of a free-body diagram?

Back

A free-body diagram visually represents all the forces acting on an object, helping to analyze the object's motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object (measured in kg), while weight is the force exerted by gravity on that mass (measured in Newtons).

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height in a gravitational field.
