What is displacement?
Displacement is the change in position of an object, measured as a straight line from the initial to the final position.
What is velocity?
Velocity is the rate of change of displacement with respect to time, including direction.
What is acceleration?
Acceleration is the rate of change of velocity with respect to time.
What is time in physics?
Time is a measure of the duration of events, typically measured in seconds.
What is the difference between scalar and vector quantities?
Scalar quantities have magnitude only (e.g., temperature, mass), while vector quantities have both magnitude and direction (e.g., velocity, force).
What is uniformly accelerated motion?
Uniformly accelerated motion occurs when an object experiences a constant acceleration.
What are the kinematic equations used for motion with constant acceleration?
The kinematic equations relate displacement, initial velocity, final velocity, acceleration, and time.
How do you determine which kinematic equation to use?
Choose the equation based on the known and unknown variables for the problem at hand.
What types of motion graphs can be analyzed?
Motion graphs include position-time, velocity-time, and acceleration-time graphs.
What is free fall?
Free fall is the motion of an object under the influence of gravity alone, with negligible air resistance.
What is the acceleration due to gravity on Earth?
The acceleration due to gravity on Earth is approximately 9.8 m/s².
How does velocity change during free fall?
During free fall, the velocity of an object increases downward with time.
What happens to a freely falling object's acceleration-time graph?
The acceleration-time graph of a freely falling object is a horizontal line at g, indicating constant acceleration.
How can you calculate the time it takes for an object to reach the ground?
Use kinematic equations considering the initial height and acceleration due to gravity.
How can you find the velocity of an object in motion?
Calculate the velocity of an object at various points using kinematic equations.
How can you determine the maximum height reached by a thrown object?
Use motion equations that account for initial velocity and acceleration due to gravity.
How do different objects fall in a vacuum?
In a vacuum, all objects fall at the same rate due to the uniform acceleration of gravity.
Why doesn't mass affect the acceleration of freely falling objects?
In the absence of air resistance, all objects fall at the same rate regardless of mass.
How does air resistance affect falling objects?
Air resistance affects objects differently based on their shape, mass, and surface area.
