What is the effect of a net force acting on an object?
The object accelerates in the direction of the net force (Newton's Second Law).
What is the effect of applying a force on an object?
According to Newton's Third Law, the object applies an equal and opposite force back.
What happens when an object experiences centripetal acceleration?
The object moves in a circular path.
What are the differences between inertial and non-inertial frames of reference?
Inertial: Newton's laws hold true, non-accelerating | Non-inertial: Newton's laws don't apply, accelerating or under strong gravity.
What is the difference between rotational velocity and rotational acceleration?
Rotational velocity: How fast an object is rotating | Rotational acceleration: How quickly the rotational velocity changes.
Differentiate between a vector and a scalar quantity.
Vector: Has magnitude and direction | Scalar: Has only magnitude.
What is the effect of applying a net force on an object?
The object accelerates in the direction of the net force (Newton's Second Law).
What is the effect of an object moving in a circle?
It experiences centripetal acceleration towards the center of the circle.
What happens when you push on a wall (Newton's Third Law)?
The wall pushes back on you with an equal and opposite force.
