An object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by an unbalanced force.
What is Newton's Second Law of Motion?
The acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
What is Newton's Third Law of Motion?
For every action, there is an equal and opposite reaction.
What is the formula to calculate force?
Force = mass x acceleration
What is the unit of force?
Newton (N)
What is friction?
A force that opposes the motion of objects that are in contact with each other.
What is inertia?
The tendency of an object to resist changes in its motion.
What is the difference between mass and weight?
Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.
What is the law of conservation of momentum?
The total momentum of a closed system remains constant if no external forces act on it.
What is the relationship between force, mass, and acceleration?
Force is directly proportional to mass and acceleration. F = ma
What is the difference between balanced and unbalanced forces?
Balanced forces have a net force of zero and do not cause a change in motion, while unbalanced forces result in a change in motion.
What is the relationship between acceleration and mass?
Acceleration is inversely proportional to mass. As mass increases, acceleration decreases.
What are some examples of forces in everyday life?
Examples include gravity, friction, applied force, tension, air resistance, etc.
What is the difference between speed and velocity?
Speed is the distance an object travels per unit of time, while velocity specifies both speed and direction.
What is terminal velocity?
The constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.

Force is directly proportional to acceleration. F = ma
