Physics, grade 10
21 topics for grade 10, 189 exercises. Each one starts with an explanation, then practice that adapts: get it right and the difficulty rises, get it wrong and the tutor takes the step apart.
Topics in this grade
Molecular Kinetic Theory
Molecular kinetic theory explains matter by describing the motion of the tiny particles it is made of.
9 exercises
Ideal Gas Laws
Ideal gas laws relate a gas's pressure, volume, and temperature to each other.
9 exercises
Capacitors
A capacitor is a device that stores electric charge and energy between two conducting plates.
9 exercises
First Law of Thermodynamics
The first law of thermodynamics is energy conservation applied to heating and work.
9 exercises
Second Law of Thermodynamics
The second law of thermodynamics says a heat engine cannot turn all its absorbed heat into useful work.
9 exercises
Phase Transitions
A liquid can turn into vapor from its surface, or throughout its volume once it starts to boil.
9 exercises
Postulates of Special Relativity
Special relativity rests on two postulates: physics laws are the same in every inertial frame.
9 exercises
Relativistic Kinematics
Relativistic kinematics describes how time and length change for objects moving at speeds close to light speed.
9 exercises
Relativistic Dynamics
Relativistic dynamics describes how an object's total energy grows as its speed approaches light speed.
9 exercises
Electric Field in Matter
Placing a conductor or a dielectric inside an electric field changes how that field behaves.
9 exercises
Measurement Uncertainty
Measurement uncertainty is how far a measured value can stray from the true value of a quantity.
9 exercises · about 25 min
Scalar and Vector Quantities
A scalar quantity is fully described by a single number, like mass or time.
9 exercises · about 25 min
Relative Velocity
Relative velocity describes how an object's velocity looks different in a moving frame than a still one.
9 exercises · about 25 min
First Cosmic Velocity
First cosmic velocity is the speed an object needs to circle a planet in a low, steady orbit.
9 exercises · about 25 min
Elastic Force and Weight
Elastic force is the push or pull a stretched or squeezed object exerts as it springs back.
9 exercises · about 25 min
Torque and Equilibrium
Torque measures how strongly a force turns an object around a pivot point.
9 exercises · about 25 min
Surface Tension and Capillarity
Surface tension is a liquid's tendency to pull its surface tight, like a stretched membrane.
9 exercises · about 25 min
Electric Potential
Electric potential measures the potential energy a charge would have at a point, per unit charge.
9 exercises · about 25 min
Fluid Dynamics
Fluid dynamics studies how liquids and gases flow through pipes and around objects.
9 exercises · about 25 min
Mechanical Properties of Solids
Mechanical properties of solids describe how a solid stretches, compresses, or bends under a force.
9 exercises · about 25 min
Electric Field Basics
Electric field strength measures how strongly an electric field pushes or pulls on a charge placed inside it.
