Force and Motion Quiz

Study Notes

Force and Motion

Force is a push or pull that can cause an object to accelerate, change its velocity, or change its shape.
Force is a vector quantity, meaning it has both magnitude (strength) and direction.
Motion is the state of change in position over time. It's described by velocity and acceleration.

Inertia

Inertia is the tendency of an object to resist any change in its motion.
Objects at rest tend to stay at rest, and objects in motion tend to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Inertia is directly proportional to mass. A more massive object has more inertia than a less massive object.

Balanced Forces

Balanced forces are forces acting on an object that are equal in size and opposite in direction.
They cancel each other out.
The net force on an object experiencing balanced forces is zero.
An object experiencing balanced forces will either remain at rest or continue to move at a constant velocity.

Unbalanced Forces

Unbalanced forces are forces acting on an object that are not equal in size and opposite in direction.
They do not cancel each other out.
The net force on an object experiencing unbalanced forces is not zero.
An object experiencing unbalanced forces will accelerate; its velocity will change. The direction of acceleration will be in the direction of the net force.

Mass

Mass is a measure of the amount of matter in an object.
Mass is a scalar quantity, meaning it only has magnitude but no direction.
Mass is a fundamental property of an object, determining its inertia (resistance to changes in motion).
Mass is not affected by gravity or location. The mass of an object is the same on Earth as it is in space.
Units of mass include kilograms (kg).
