Gravity, friction, or wind drag.
Presence of friction, incline and so on.
No, it causes a huge decrease in speed.
If you increase the number of bulbs in a circuit, the resistance in the circuit will increase, causing the motor's speed to decrease. If you decrease the number of bulbs, the resistance in the circuit will decrease, causing the motor's speed to increase.
Speed can decrease due to forces like friction, air resistance, or gravity acting in the opposite direction to the motion. Additionally, factors like an increase in mass or a change in the surface conditions can also cause speed to decrease.
If you are referring to the voltage at your residence, then voltage variation is caused by the changes to the load on your supply network. The network load varies throughout the day, being busiest, for example, around lunchtime and around dinnertime. The resulting load current variation causes the supply voltage to vary (it drops when the load current increases) but, by law, your supplier is obliged to maintain any voltage variation within limits -in the UK, for example, these limits are between +10% and -6% of the nominal 230 V.
Since kinetic energy depends on mass and speed, you can increase either of these.
Pressure has a direct relationship with the speed of sound, which in turn affects the frequency of a wave. As pressure increases, the speed of sound increases. This causes the wavelength to decrease, resulting in an increase in frequency. Conversely, a decrease in pressure would lead to a decrease in frequency.
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
When a force causes the speed of an object to decrease, it is known as deceleration or negative acceleration. The object's velocity decreases over time until it eventually comes to a stop, depending on the magnitude of the force and the mass of the object.
no the strength of the magnetic field does not decrease because of the number of coils increases.
electrons
No, they Increase the speed of chemical reactions
