What causes a change in an objects motion
balanced force
unbalanced force
acceleration
inertia
A change in an object's motion can be caused by a few factors:
1. Balanced force: When the net force acting on an object is zero, it experiences balanced forces. In this case, the object remains at rest or continues to move at a constant velocity.
2. Unbalanced force: If the net force acting on an object is not zero, it experiences unbalanced forces. This causes the object to accelerate or decelerate, resulting in a change in its motion. The direction and magnitude of the force determine the direction and rate of acceleration.
3. Acceleration: Acceleration refers to the rate at which an object's velocity changes over time. A change in motion occurs when an object experiences non-zero acceleration, either in the form of speeding up, slowing down, or changing direction. Acceleration is directly proportional to the net force applied to an object and inversely proportional to its mass. This means that larger forces or smaller masses result in greater acceleration.
4. Inertia: Inertia is the tendency of an object to resist changes in its motion. It can be thought of as the "stay in motion" or "stay at rest" property of an object. The more massive an object, the greater its inertia, making it more resistant to changes in its motion. Inertia also plays a role in determining how an object responds to different forces and accelerations.
