gcse physics forces and motion revision notes

So any force that causes a body to move is an unbalanced force. The centripetal force always acts toward the centre of the circle. The r.m.s voltage is about 70% of the peak voltage, An alternating current is I is represented by the equation, Step 1: Write out the equation for r.m.s current, Step 3: Substitute into the Ir.m.s equation. GCSE Science Revision Guides & Study Notes. 20.1.9 Velocity Selection. Example. Centripetal Force. Remember: If the resultant force on an object is zero, the object will remain stationary or continue to move at a steady speed in the same direction. Designed by the teachers at SAVE MY EXAMS for the Edexcel GCSE Physics syllabus. A GCSE video on motion, speed, distance, time, acceleration and motion graphs. Drivers should not drive closer than the thinking distance to the car in front, allowing them time to react. If the velocity of the object increases. Objects in free fall have a constant acceleration of 10 m/s2, This video explains the effects of Gravity. This video explains about the effects of air resistance. Here are a list of themes and the suggested poems which can be linked to these themes (Source: CGP Power and Conflict revision guide). From Newtons first law of motion it is known that an object will remain stationary, or keep moving at constant velocity in a straight line unless acted upon by an unbalanced force. 24.1.5 Attenuation of Ultrasound in Matter, 1.1.3 Homogeneity of Physical Equations & Powers of Ten, 2.1.1 Displacement, Velocity & Acceleration, 2.1.4 Gradient of a Displacement-Time Graph, 2.1.7 Solving Problems with Kinematic Equations, 2.1.8 Acceleration of Free Fall Experiment, 4.1 Forces: Turning Effects & Equilibrium, 5.1 Energy: Conservation, Work, Power & Efficiency, 5.1.2 The Principle of Conservation of Energy, 6.2 Deformation: Elastic & Plastic Behaviour, 7.2 Transverse Waves: EM Spectrum & Polarisation, 10.1 DC: Practical Circuits & Kirchhoff's Laws, 10.1.6 Solving Problems with Kirchhoff's Laws, 12.1 Kinematics of Uniform Circular Motion, 12.2.2 Calculating Centripetal Acceleration, 13.1.2 Gravitational Force Between Point Masses, 13.1.3 Circular Orbits in Gravitational Fields, 15.2.2 Derivation of the Kinetic Theory of Gases Equation, 15.2.3 Average Kinetic Energy of a Molecule, 17.1.3 Calculating Acceleration & Displacement in SHM, 18.1.1 Electric Fields & Forces on Charges, 18.1.5 Electric Force Between Two Point Charges, 19.1.4 Area Under a Potential-Charge Graph, 20.1.2 Force on a Current-Carrying Conductor, 20.1.8 Motion of a Charged Particle in a Magnetic Field, 20.1.10 Magnetic Fields in Wires, Coils & Solenoids, 20.1.11 Forces between Current-Carrying Conductors, 20.2.3 Principles of Electromagnetic Induction, 21.1 Properties and Uses of Alternating Current, 21.1.2 Root-Mean-Square Current & Voltage, 23.1 Mass Defect & Nuclear Binding Energy, 23.1.5 Calculating Energy Released in Nuclear Reactions, 23.2.1 The Random Nature of Radioactive Decay, 24.2.3 Detecting Gamma-Rays from PET Scanning, 25.1.2 Standard Candles & Stellar Distances, 25.1.4 Stefan-Boltzmann Law & Stellar Radii, 25.2.3 Hubble's Law & the Big Bang Theory, The attenuation coefficient of the ultrasound is expressed in, Generally, 0.5 dB/cm is lost for every 1MHz, The intensity I of the ultrasound decreases with distance, The absorption coefficient , will vary from material to material, Attenuation is not a major problem in ultrasound scanning as the scan relies on the reflection of the ultrasounds at boundaries of materials, Attenuation from the surface S to the fat-muscle boundary, Attenuation from the boundary back to the surface S. This diagram shows the shortest stopping distances at different speeds. She decided that she wanted to inspire other young people, so moved to Bristol to complete a PGCE in Secondary Science. You would slip back and never move forward. A man blows into one end of a U-tube containing water until the levels differ by 40.0 cm. Weight is a force and is measured innewtons.

This arises because, on a microscopic scale, thesurfaces are not completely smooth and the high points become stucktogether. This is called the resultant force. Measure from the central fringe across many fringes using the vernier callipers and divide by the number of fringe widths to find the fringe width, Repeat the experiment twice more and calculate and record the mean fringe width w for each distance, Comparing this to the equation of a straight line: y = mx.

Newton's three laws of motion are explained and their application to the analysis of the motion of objects in one dimension is discussed. On theMoon, which has less mass than the Earth, the gravitational attraction is less, soobjects will have less weight than they have on the Earth (only one sixth). An anti-lock braking system (ABS) helps to keep the stopping times to a minimum. When speed doubles, thinking distance doubles, and braking distance is four times as far.

She particularly loves creating fun and absorbing materials to help students achieve their exam potential. Assuming them to be point charges, calculate the magnitude of the electrostatic force acting on each of the charges.Atomic number of helium = 2Atomic number of gold = 79Charge of an electron = 1.60 10-19 C, The charge of one proton = +1.60 10-19 C, An alpha particle (helium nucleus) has 2 protons, Step 2: The electrostatic force between two point charges is given by Coulombs Law, Step 3: Substitute values into Coulomb's Law.
