How can voyager 1 didn't run out of fuel?
Once an object is moving in space, no fuel is needed tokeep it going, only to change its speed or direction.
How much heat in joules is needed to raise the temperature of 5 grams of iron?
Q = m x Cp x temp change then: Temp change = m x Cp / Q where: m = mass of matter Cp =specific heat of matter Q= heat
How much force is needed to keep a 2kg object moving?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
What is needed to change a phase of matter?
To change a phase of matter, energy must be added or removed from a substance. For example, adding heat can cause a solid to melt into a liquid or a liquid to evaporate into a gas. Conversely, removing heat can condense a gas into a liquid or freeze a liquid into a solid. These changes typically involve alterations in temperature and pressure, influencing the arrangement and movement of particles.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
What is needed to change the direction of a moving mass?
To change the direction of a moving mass, you need to apply a force in the opposite direction to the mass's current velocity. This force can come from various sources such as friction, gravity, or an external force like pushing or pulling. The magnitude and direction of the force will determine how quickly and effectively the mass changes its direction.
If an object is moving at a constant speed in one direction what is needed to change the speed direction?
To change the speed or direction of an object moving at a constant speed, an external force is required. This force can come from a push, pull, or any other interaction that can accelerate or decelerate the object in a different direction.
If an object is moving at a constant speed in one direction what is needed to change its speed or direction?
To change the speed or direction of an object moving at a constant speed, a force must be applied in the opposite direction of its motion to slow it down and a force must be applied in the desired direction of its new path to change its direction. The magnitude and direction of the force will determine how much the speed or direction changes.
What is the rate at which an object is moving at a given instant called?
speed if no direction is needed velocity if direction is needed

What is needed to change its speed or direction?
Force
What is the amount of push and pull which can change speed and direction of moving objects?
The amount of push and pull needed to change the speed and direction of a moving object depends on the mass of the object and the magnitude and direction of the force applied. Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. To change the speed and direction of an object, a force greater than the object's current momentum is required.
Why is more force needed to change the motion of a heavy and fast moving object compared to a light weight and slow moving obect?
More force is needed to change the motion of a heavy and fast-moving object because of its momentum, which is the product of its mass and velocity. The momentum of an object indicates the amount of force required to change its motion, so heavier objects with higher velocities require more force to change their direction or speed compared to lighter objects moving at slower speeds.
Can a fixed pulley change direction of load?
No, a fixed pulley cannot change the direction of the load. It only changes the direction of the force needed to lift the load.
What is needed for matter to change it's state?
Energy
What is needed to change speed into a velocity?
You have a velocity when both a speed and a direction is specified. This kind of magnitude is known as a "vector" - that is, when it is relevant to state a direction, as well as a magnitude, we speak about "vectors".
Which machine changes the direction of force needed to do a task without changing the size of force needed?
A pulley can do that.
