Forces & Motion
This quantity equals mass times acceleration.
What is force?
The energy an object has because it is moving.
What is kinetic energy?
The number of waves passing a point each second.
What is frequency?
The flow of electric charge through a circuit.
What is current?
Density is calculated using mass divided by this quantity.
What is volume?
A moving car with zero net force continues at constant velocity because of this law.
What is Newton’s First Law?
This happens to kinetic energy when friction acts on a moving object.
What is conversion to thermal energy?
Sound cannot travel through outer space because it needs this.
What is a medium?
In a series circuit, this happens when one bulb burns out.
What is the whole circuit goes out?
Rust forming on iron is this type of change.
What is a chemical change?
On a velocity-time graph, the slope represents this quantity.
What is acceleration?
Power is calculated by dividing work by this quantity.
What is time?
Light bending as it moves between materials is called this.
What is refraction?
Voltage divided by resistance gives this quantity.
What is current?
An object less dense than water will do this.
What is float?
A flat horizontal line on a distance-time graph represents this kind of motion.
What is no motion?
This type of energy increases when an object is lifted higher above the ground.
What is gravitational potential energy?
This type of electromagnetic wave has the greatest frequency.
What are gamma rays?
Adding more coils to an electromagnet changes the magnetic field in this way.
What is it becomes stronger?
This state of matter is a high-energy ionized gas.
What is plasma?
A 10 kg object accelerates at 4 m/s². This is the net force acting on it.
What is 40 N?
A 5 kg object lifted 4 meters gains this much gravitational potential energy.
What is 200 J?
A wave with a speed of 300 m/s and frequency of 100 Hz has this wavelength.
What is 3 meters?
A 24 V circuit with a resistance of 8 Ω has this current.
What is 3 A?
A substance with high viscosity flows in this way compared to low-viscosity liquids.
What is more slowly?
