Questão | Responda |
Speed | Speed = Distance / Time |
Distance Travelled | Distance Travelled = Average Speed x Time |
Acceleration | Acceleration = Change in Velocity / Time Taken |
Force | Force = Mass x Acceleration |
Weight | Weight = Mass x Gravitational Field Strength |
Efficiency | Efficiency = Useful Energy / Total Energy |
Momentum | Momentum = Mass x Velocity |
Wave Speed | Wave Speed = Frequency x Wavelength or Wave Soeed = Distance / Time |
Density | Density = Mass / Volume |
Work Done | Work Done = Force x Distance (moved in the direction of the force) |
Change in Gravitational Potential Energy | Change in Gravitational Potential Energy = Mass x Gravitation Field Strength x Change in Height |
Kinetic Energy | Kinetic Energy = 1/2 x Mass x Speed squared |
Power | Power = Word Done / Time Taken or Power = Energy Transferred / Time Taken |
Energy Transferred | Energy Transferred = Charge Moved x Potential Difference |
Charge | Charge = Current x Time |
Potential Difference | Potential Difference = Current x Resistance |
Electric Power | Electric Power = Current x Potential Difference or Electric Power = Current squared x Resistance |
Force Exerted on a Spring | Force Exerted on a Spring = Spring Constant x Extension |
Moment of a Force | Moment of a Force = Force x Distance (normal to the direction of the force) |
Pressure | Pressure = Force (normal to surface) / surface area |
