Term1/12

What is kinetic energy

Definition1/12

Kinetic energy is the energy that an object has due to its motion or movement. For instance if a car drives into a wall the energy of its movement is what destroys the wall, That energy is kinetic energy.

Note: Heat is also a form of Kinetic energy because heat is the movement (vibration energy) of atoms or molecules.

Which form of energy is due to the movement of electrons

Definition1/12

ELECTRICAL

Term1/12

Which of the following expressions are correct for impulse

Definition1/12

F the triangle thingy and t

the triangle thingy then p

Term1/12

Everything in or on water pushes some water aside even if it's just a little bit What is this called

Definition1/12

This is called "displacement", as the weight of water that moves is equal to the weight of the object on the water. Heavier objects displace more water. If the total weight of the object is greater than the water displaced by its volume, it is denser than water, and sinks.

Term1/12

Is momentum a vector quantity because it includes velocity which is also a vector quantity

Definition1/12

yes, momentum is a vector quantity.

Term1/12

According to the Impulse-Momentum Theorem what does impulse equal

Definition1/12

change in momentum

Term1/12

Spaceship 1 and Spaceship 2 have equal masses of 200 kg They collide Spaceship 1's final speed is 2 ms and Spaceship 2's final speed is 1 ms in the same direction What is their combined momentum

Definition1/12

2,000 kg-m/s "Apex"

Term1/12

How much work must be done on a 5 kg snowboard to increase its speed from 2 ms to 4 ms

Definition1/12

work=mass*speed,5*2=10

Term1/12

Spaceship 1 and Spaceship 2 have equal masses of 150 kg Spaceship 1 has a speed of 0 and Spaceship 2 has a speed of 6 They collide and stick together What is their speed

Definition1/12

3 m/s

Term1/12

Spaceship 1 and spaceship 2 have equal masses of 300kg spaceship 1s has a speed is 0 ms and spaceship 2 has a speed of 4 ms. they collide and stick together. what is their speed

Definition1/12

2 m/s

Term1/12

Whih of the following is not a reason why gravity is important in our lives

Definition1/12

It keeps water molecules together in a cup.

Term1/12

What do we call a collection of matter that does not interact with anything else in the universe
