Newton's second law - true vs false

If there is no net force acting on an object, it must be at rest

False : velocity is constant

An object that is at rest for a prolonged period of time has no net force acting on it

True

If there is no net force acting on an object, its velocity must remain constant

True

An object that is moving at a constant velocity has no forces acting on it

False : it has no net forces acting on it

A ball is thrown up. On its way up, its velocity and acceleration both point up.

False : only if it has no NET forces

If the net force on an object points to the right, the force of kinetic friction must point to the left

False : only if the motion of an object points to the right

When the velocity and the acceleration point in the same direction, the object must be speeding up.

True
