Basics of Motion
What is the definition of displacement?
Displacement is the change in position of an object in a particular direction.
Change in Position divided by change in Time = ?
Average Velocity
What is Newton's third law of motion?
Newton's third law states that for every action, there is an equal and opposite reaction.
What is a Acceleration due to gravity
Free-Fall acceleration
Define terminal velocity.
Terminal velocity is the constant velocity reached by an object falling through a fluid when the force of air resistance equals the force of gravity.
What is uniform motion.
Uniform motion is when an object travels equal distances in equal intervals of time.
Final Position - Initial position = ?
Displacement
Explain the concept of friction.
Friction is the force that opposes the relative motion or tendency of such motion of two surfaces in contact.
Do objects that are falling in free-fall move faster, slower, or at a constant velocity.
Faster
Describe the motion of an object in uniform acceleration.
In uniform acceleration, the velocity of an object changes at a constant rate over time.
What is velocity.
Velocity is the rate of change of displacement with respect to time. It includes both magnitude and direction.
Total Distance traveled divided by the Time = ?
Speed
Differentiate between static and kinetic friction.
Static friction occurs between two surfaces that are not moving relative to each other, while kinetic friction occurs between two surfaces that are sliding past each other.
What is the acceleration of a ball when it is thrown upwards and reaches its maximum height.
-9.8m/s^2
What is meant by a reference frame?
A reference frame is a coordinate system used to describe the motion of objects relative to a fixed point or another object.
What is the difference between speed and velocity.
Speed is the rate of change of distance with respect to time, while velocity is the rate of change of displacement with respect to time and includes direction.
What is Newton's second law of motion?
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 (F=ma).
What is the coefficient of friction?
The coefficient of friction is a dimensionless quantity representing the ratio of the force of friction between two surfaces to the force pressing them together.
Explain the Concept of Free-Fall
Downward movement under the force of gravity only.
What are the key differences between distance and displacement?
Distance is the total length of the path traveled by an object, while displacement is the straight-line distance between the initial and final positions of the object.
What is acceleration?
Acceleration is the rate of change of velocity with respect to time.
How many m/s^2 is the acceleration due to gravity on Earth
9.81 m/s^2
Describe the motion of an object with zero acceleration.
An object with zero acceleration maintains a constant velocity and does not change its speed or direction.
What is the formula for calculating change in velocity of Free-Fall objects.
V = AT
What is the role of mass in Newton's second law of motion?
Mass is the measure of inertia of an object and plays a crucial role in determining the acceleration of an object under the influence of a given force.
