Which of the following is a scalar quantity?
The SI unit of force is:
According to Newton's First Law of Motion, an object at rest will remain at rest, and an object in motion will continue moving with the same velocity, unless acted upon by an external force.
The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the object's mass.
For every action, there is an equal and opposite reaction.
The motion of an object can be described by its position, velocity, and acceleration.
The velocity of an object is the rate at which its position changes over time.
Acceleration is the rate at which an object's velocity changes over time.
In projectile motion, the horizontal component of velocity remains constant throughout the motion.
The range of a projectile is the maximum horizontal distance it travels before returning to the ground.
Friction is a force that opposes the relative motion of two surfaces in contact.
The coefficient of friction is a dimensionless quantity that represents the ratio of the force of friction to the normal force between two surfaces.
Rolling friction is generally less than sliding friction.
Air resistance is a type of drag force that opposes the motion of an object through a fluid.
The buoyant force is an upward force exerted by a fluid on an object immersed in it.
