• Unbalanced

• Balanced

• Friction

• Gravitational

Answer explanation

A change in Position over time is the definition of what?

• Motion

• Velocity

• Acceleration

• Gravity

Answer explanation

What will happen if a Net Force of 0 is applied to an object?

• It will move down

• It will stay still

• It will move up

• It will move all over

Answer explanation

If a net force of 0 is applied, the object will stay still. This is because the forces acting on the object are balanced, resulting in no motion.
