Science 8 MidSem Review

The resistance of an object to a change in its state of rest or uniform motion.

• Acceleration

• Energy

• Inertia

• Force

Which of the following is NOT true about the second law of motion, law of acceleration?

• The net force acting on an object is a product of its mass and acceleration.

• With the mass held constant, greater force results to greater acceleration.

• With the force held constant, greater mass results to lesser acceleration.

• With the acceleration held constant, greater force results to greater mass.

The third law of motion, law of interaction, states that:

• For every action, there is an equal reaction.

• For every action, there is an opposite reaction.

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

• For every action, there is a greater reaction in the same direction.

This law states that: An object at rest will stay at rest, and an object in motion will stay in motion at constant velocity, unless acted upon by an unbalanced force.

• Law of Acceleration

• Law of Force

• Law of Inertia

• Law of Interaction

This law describes the relationship between voltage (V), current (I), and resistance (R).

• Joule's Law

• Newton's Law

• Ohm's Law

• Volts' Law

The greater the mass of an object, the greater is its inertia.

• TRUE

• FALSE

The greater the force, the greater the acceleration of a body with the same mass.

• TRUE

• FALSE

The lesser the mass, the greater is the acceleration of a body acted upon by the same net force.

• TRUE

• FALSE

Heat flows from a body of lower temperature to a body of higher temperature.

• TRUE

• FALSE

Heat transfer requires temperature difference between two bodies.

• TRUE

• FALSE
