Forces must be greater than zero and impact the object.
What else can I help you with?
What must be true about the forces acting on an object if the motion of the object does not changes?
The forces must be balanced; the forces must be equal in size and opposite in direction. (Net force must equal zero).
Must an object always have the same motion?
No, of course not! We ourselves we change our motion!
What must be true about the force acting on an object if the motion of the object does not change?
The forces must be balanced; the forces must be equal in size and opposite in direction. (Net force must equal zero).
When you measure an object's resistance to motion you must measure what?
Inertia is an objects resistance to change in motion. Frictional forces resist motion.
What must be applied to an object to change its motion or direction?
If an object is at rest, a force must be applied to accelerate it (start it moving).
A object in motion must undergo a change in?
A object in motion must undergo a change in velocity, meaning its speed, direction, or both. This change is known as acceleration, which can occur due to forces acting on the object such as gravity or friction.
What forces produce no change in the motion of an object?
When the forces acting on an object are balanced, there is no change in the object's motion. This means that the net force on the object is zero, allowing it to maintain a constant velocity or remain at rest. Examples of forces that can produce no change in motion include frictional forces and tension in a stationary object.
What must be applied to an object to change its direction?
A force must be applied to an object in order to change its direction. By exerting a force at an angle to the object's initial direction of motion, the object will change its path and move in a different direction.
What must be changed in order to change the motion of an object?
To change the motion of an object, one must apply a force to it. The magnitude and direction of the force will determine how the motion changes. More force will cause a greater change in motion, and changing the direction of the force will also change the direction of motion.
What conditions must exist for an object to be in uniform motion?
In order for an object to be in constant uniform motion ... that is, un-accelerated, with constant speed and direction of motion ... the vector sum of all forces acting on it must be zero.
How do unbalanced forces affect motion?
-- An unbalanced group of forces on an object causes the object to accelerate in the direction of the net force. -- If an object is not moving, then the group of forces on it must be balanced, else it would be accelerated.
An object's motion remain's constant when acted upon by what?
When there is no net force - if there are any forces, the sum of all the forces must be zero.
