Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
Answer:
Explanation:
The law of inertia states that if an object is in motion will remain in motion unless an external force is applied to it.
law of inertia for the rotating system in terms of angular momentum states that the angular momentum of a system will remain the same unless an external torque is applied to the system.
External Torque either increases or decreases the angular velocity thus changing angular momentum.
Answer:
Electrons
Explanation:
The electrons are called the subatomic particles. The electrons have one of the symbol of e-and β-. The electrons are the first generation of the Lepton particles. These are generally describe the elementary particles. These particles do not have components and substructure.
Like all other elements the electrons also exhibits some types of properties. These electrons also hit with another particles and start to diffracted in different direction like lights.
The wave property of the electrons can be observed with the help of experiment.
When you exert a force on the coin, it will accelerate. If you push the coin and it moves at a constant velocity, the friction force must be equal to the force that you are exerting. This is an example of a balanced force. When the net force is greater than 0 N, the is an unbalanced force.
