Honors Physics Midterm Questions with
Certified Answers
What is the difference between speed and velocity?
✔✔ Speed is the measure of how fast an object is moving, while velocity includes both the speed
and the direction of the object's motion.
How does Newton's Third Law of Motion apply to interactions between two objects?
✔✔ Newton's Third Law of Motion states that for every action, there is an equal and opposite
reaction, meaning that when one object exerts a force on a second object, the second object
exerts a force of equal magnitude and in the opposite direction on the first object.
What is the principle of conservation of momentum?
✔✔ The principle of conservation of momentum states that the total momentum of a closed
system remains constant if no external forces act on it.
How is work defined in physics?
✔✔ Work is defined as the transfer of energy that occurs when a force moves an object over a
distance.

,What is the role of gravity in free-fall motion?
✔✔ Gravity causes objects to accelerate downward at a constant rate during free-fall, regardless
of their mass.
What factors affect the period of a pendulum?
✔✔ The period of a pendulum is affected by the length of the pendulum and the acceleration due
to gravity, but not by the mass of the pendulum.
What is the difference between elastic and inelastic collisions?
✔✔ In elastic collisions, both kinetic energy and momentum are conserved, whereas in inelastic
collisions, only momentum is conserved and some kinetic energy is transformed into other forms
of energy.
How does friction affect the motion of an object?
✔✔ Friction opposes the motion of an object, causing it to slow down and eventually stop.
What is the concept of inertia?
2
, ✔✔ Inertia is the tendency of an object to resist changes in its state of motion, whether it is at
rest or moving.
What does the term "momentum" refer to in physics?
✔✔ Momentum refers to the quantity of motion an object has, which depends on both its mass
and velocity.
What is the definition of acceleration?
✔✔ Acceleration is the rate at which an object's velocity changes over time.
How does centripetal force act on an object moving in a circular path?
✔✔ Centripetal force acts towards the center of the circular path, keeping the object moving in
that circle.
What is the difference between scalar and vector quantities?
✔✔ Scalar quantities have only magnitude, such as temperature or mass, while vector quantities
have both magnitude and direction, such as velocity or force.
