What else can I help you with?
What must happen for an object that is already moving to change its speed or direction?
For an object to change its speed or direction, a force must be applied to it. The magnitude and direction of the force will determine how the object's speed or direction changes. This change in motion is described by Newton's laws of motion.
What must happen for acceleration to occur?
For acceleration to occur, there must be a change in an object's velocity over time. This change can happen by increasing or decreasing the object's speed or by changing its direction of motion. In essence, acceleration is a measure of how much an object's velocity changes per unit of time.
What must happen to move an object at rest?
An external force must be applied to the object in order to overcome inertia and initiate motion. This force must be greater than any frictional or opposing forces acting on the object to cause it to start moving.
An object is traveling in a straight line in space no forces are acting on the object based on this evidence what will happen to the objects motion?
Nothing will happen to the object's motion, it will continue along its path.
What happen to the speed of moving object when it is pushed in the direction of motion?
When a moving object is pushed in the direction of its motion the speed of the object increases
According to the scientific definition for work what must happen in order for work to be accomplished?
In order for work to be accomplished, there must be a force applied to an object and the object must move in the direction of the force. Work is the product of the force applied to an object and the distance over which the force is applied.
What must happen to an object if a force does not work on it?
If a force does not work on an object, the object will either remain at rest or continue moving at a constant velocity in a straight line, according to Newton's first law of motion.
An object that has kinetic energy must be what?
In motion
What forces must be changed the motion of an object?
Forces must be greater than zero and impact the object.
What has to act on an object for it to stay in motion?
An external force must act on an object for it to remain in motion. According to Newton's first law of motion, an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an external force.
What factors are necessary for an object to be in motion?
Inertia is required for an object to be in motion, which is the tendency of an object to resist changes in its state of motion. Additionally, an external force must be applied to overcome any friction or resistance that may impede the object's motion.
If a force of 100 newtons was exerted on an object and no work was done the object must have?
If no work was done, the object must not have moved in the direction of the force. This could happen if the force was applied perpendicular to the object's motion or if the object remained stationary.
