Motion at a changing speed.
Displacement: This refers to the change in position of an object from its initial to final position.
Velocity: This is the rate of change of displacement over time.
Acceleration: This is the rate of change of velocity over time.
Uniform motion: This occurs when an object moves with constant velocity or zero acceleration.
Non-uniform motion: This occurs when an object's velocity changes over time.
Scalars and vectors: Scalars are quantities in physics such as time and temperature that have only magnitude, while vectors like displacement and velocity have both magnitude and direction.
Position-time graphs: These are graphical representations of an object's position over time.
Speed-time graphs: These are graphical representations of an object's speed over time.
Calculating displacement and velocity from position-time graphs.: Calculating displacement and velocity from position-time graphs involves determining the change in position and the average rate of change in position over time, respectively, by analyzing the graph's slope and area under the curve.
Calculating acceleration from velocity-time graphs.: Calculating acceleration from velocity-time graphs involves determining how quickly an object's velocity changes over time by finding the slope of the graph.
Projectile motion: This is a type of motion where an object is launched into the air and moves in a curved path under the influence of gravity.
Newton's laws of motion: These are fundamental laws that describe the behavior of objects in motion.
Friction: This is a force that opposes the motion of an object.
Air resistance: This is a type of friction that is experienced by objects in motion through the air.
Terminal velocity: This is the maximum velocity that an object can reach in free fall due to air resistance.
Kinematic equations: These are mathematical formulas that relate various kinematic variables such as displacement, velocity, and acceleration.
Relative motion: This is the study of motion with respect to a reference frame or observer.
Galilean transformation: This is a mathematical transformation used to relate motions in different reference frames.
Special theory of relativity: This is a theory developed by Albert Einstein that describes the behavior of objects at high speeds.
Doppler effect: This is a phenomenon where the frequency of a wave appears to change when the source of the wave is moving.
Uniformly accelerated motion: This is the most common type of non-uniform motion, where an object's velocity changes at a constant rate. For example, an object that starts moving from rest and gradually speeds up over time.
Non-uniformly accelerated motion: This is a type of motion where an object's velocity changes at varying rates over time. For example, an object that experiences a variable force, such as a rocket during takeoff, would undergo non-uniform acceleration.
Projectile motion: This is the motion of an object that is launched into the air, moving along a curved path due to the force of gravity. This type of motion can be seen when a ball is thrown or when a cannon fires a shell.
Circular motion: This is the motion of an object moving along a circular path. For example, a car driving around a roundabout or a planet orbiting a star.
Oscillatory motion: This is the motion of an object that moves back and forth periodically, such as a pendulum and a spring.
Relative motion: This is the motion of one object compared to another. For example, an object in motion on a moving train would appear to be moving differently to an observer outside the train.
Rolling motion: This is the motion of an object that rolls along a surface, such as a ball rolling down a hill or a wheel turning on an axle.
Translational motion: This is the motion of an object that moves in a straight line, such as a car on a highway or a person walking in a straight line.
Rotational motion: This is the motion of an object that rotates around an axis, such as a spinning top or the Earth rotating on its axis.
Vibrational motion: This is the motion of an object that vibrates or oscillates about a fixed point, such as a guitar string or a tuning fork.
