Impulse and Momentum
The momentum of an object will double if you do this to its velocity
What is Double the Velocity?
This law explains how to calculate the gravitational force between two objects.
What is Newton's Law of Universal Gravitation?
This particle carries the NEGATIVE charge in nature.
What is the electron?
This is the result when a bar magnet is cut into two pieces down the middle.
What is two smaller magnets are created?
This is the maximum height of the wave from equilibrium position.
What is amplitude?
When we apply this to an object, its momentum changes.
What is Impulse?
If a moon moves three times further away from a planet, then this happens to the gravitational force between it and the planet.
What is decreases by nine times?
This kind of charge on an object leads to it experiencing an acceleration away from a negatively charged ball.
What is a negative charge?
This is the part of a magnet where the magnetic field is the strongest.
What is the pole of the magnet?
This is the technical term for the the time taken by the wave to complete one cycle.
What is period?
This technology is used in modern cars to reduce the force acting on the passengers during a collision, by increasing the time over which the car comes to a rest.
What is a crumple zone?
This real force provides the centripetal force required to keep cars moving in a circular road.
What is friction?
This universal constant is used to estimate the electrostatic force between two charged objects.
What is Coulomb's constant?
This word is used to define microscopic regions inside a metal where the tiny magnets of the electrons all point in the same direction.
What are magnetic domains?
This universal constant has a value of 3 x 10^8 m/s.
What is the speed of light in vacuum?
This law helps us predict the velocity with which an object would travel after it collides with an identical object at rest.
What is the Law of Conservation of Momentum?
This is the direction in which centripetal force acts, in all situations involving circular motion.
What is radial/in towards the center of the circle?
In this type of charging, physical contact between a charged object and a neutral object leads to both of them developing the same charge.
What is conduction?
This device is used to convert mechanical energy into electrical energy, using a magnet and a coil of wire.
What is a generator?
This type of wave propagates perpendicular to the direction of the oscillating particle.
What is a transverse wave?
One way to increase the force of impact during a collision is to shorten the time of the collision. The other ways to do it is this.
What is Increasing the change of momentum (∆p) that will occur during the collision?
If the gravitational force between two objects increases and becomes 16 times stronger, we can come to this conclusion.
What is the objects were moved 4 times closer to each other?
In a electric field map, this type of charge is represented by a small circle with arrows coming out of it.
What is a positive charge?
When an iron core is wrapped with a coil of copper wire and a current is passed through it is, it gets temporarily magnetized, becoming this device.
What is an electromagnet?
Sound waves are an example of these type of waves which cannot exist in deep space.
What is a mechanical wave?
