A car needs energy to move at a steady speed because it needs to equalize the force of air pressure by moving forward.
The speed of a wave is a property of the medium, changing the speed would need a change in the medium itself. If the medium doesn't change as a wave moves, the wave speed is steady. Formula: Speed = distance divided by time
No, a person can not run at the speed of light. To make something move faster and faster you need more and more energy, and the more mass it has, even more energy it needs to move. The reason why light can travel at its own speed is because it has no mass, and it would take an infinite amount of energy to make something with even the slightest amount of mass to make something move at the speed of light.
Aircraft need a force from their engines to counteract the drag force that acts against them as they move through the air. This force is necessary to maintain a steady speed and keep the aircraft in level flight.
The cilia need energy provided by the mitochondrion to move. The other cells do not move do not have the need for the same amount of energy.The cilia need energy provided by the mitochondrion to move. The other cells do not move do not have the need for the same amount of energy.
Kinetic energy = (1/2)*mass*(speed)^2 where, in metric units, mass is in kilograms, speed is in meters/second, and kinetic energy is in Joules. So, you need to know the mass and the speed of the things.
Yes, everything needs energy to move.
They need the force to overcome the friction between the lorry and the road.
because Iguanas need to save energy and heat, and they do that by not moving a lot. they need the energy when they do have to move.
You need potential energy for it to move foreward.
kittens move because they need to move so thay can have energy
i don't know. i need a answer!
