PHYSICAL SCIENCE PRACTICE EOC

Front

What is the primary ability of all waves?

Back

All waves have the ability to transfer energy.

Front

Which force is NOT one of the four fundamental forces?

Back

Friction is NOT one of the four fundamental forces.

Front

How do you calculate the force required to accelerate an object?

Back

Force (F) = mass (m) × acceleration (a). For example, a car with a mass of 3000 kg accelerated at 2 m/s² requires 6000 N of force.

Front

What does the Law of Conservation of Mass state?

Back

Mass cannot be created or destroyed in a chemical reaction.

Front

If a student kicks a ball with a force of 500 N, what force does the ball apply on the student?

Back

The ball applies a force of 500 N back on the student, according to Newton's Third Law of Motion.

Front

What is energy transfer in waves?

Back

Energy transfer in waves refers to the movement of energy from one place to another without the transfer of matter.

Front

List the four fundamental forces in nature.

Back

1. Gravity 2. Electromagnetic force 3. Strong nuclear force 4. Weak nuclear force.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.
