Answer 1

Quantity chart

Definition	Quantity	Unit	Scalar or vector	Explaination
Force through a displacement.	Work	J	scalar	W=F.S Since it is the dot product of F and S it is a scalar .
The gravitational force Earth exerts on an object	Weight	N	Vector	W=mg Since it is a force it is a vector quantity.
Change in position.	Displacement	m	Vector	S=v×t It depends on the direction of motion.
The combination of on object’s mass and velocity.	Momentum	kgm/s	Vector	P=mv It depends on direction of velocity which is a vector
The ability to do work	Energy	J	Scalar	Energy is equivalent to the work. Therefore it is a scalar
Speed and direction.	Velocity	m/s	Vector	V=S/t It depends on the direction of displacement which is a vector.
How fast an object changes how fast it’s going.	Acceleration	m/s^2	Vector	rate of change of velocity is acceleration. It depends on the direction of velocity
The force perpendicular to surface of contact.	Normal force	N	Vector	It is a force. Therefore it has direction.
The rate at which work is done.	Power	W	Scalar	P=W/t It is the ratio of two scalar quantities. So it is also a scalar
A force parallel to the surface of contact opposing motion.	Frictional force	N	Vector	Friction is an opposing force. Since it is a force it is a vector
The amount of matter an object is made of.	Mass	kg	Scalar	Mass doesn't have any direction.
