The acceleration due to gravity is approximately "9.8 m/s²"
True – This is the accepted standard near Earth’s surface.
A force acting on a stationary object will always cause it to move
False – If forces are balanced, the object may remain at rest.
The equation "F = ma" relates force, mass, and acceleration
True – It’s Newton’s Second Law.
Velocity and speed are the same if the direction is ignored
True – Speed is the magnitude of velocity.
If the resultant force on a body is zero, the body must be at rest
False – It may move at a constant velocity.
The displacement of a particle is the shortest distance from the initial to final position
True – Displacement is a vector between two points.
The unit of force is the newton, abbreviated as "N"
True – Standard SI unit of force.
In vertical projectile motion, the object’s speed is zero at the highest point
False – Speed is zero only if it momentarily stops, but velocity changes direction.
The tension in a light inextensible string is the same throughout its length
True – This is a common assumption in mechanics.
The direction of the weight vector always points vertically downward
True – Weight acts due to gravity.
A displacement-time graph with a constant positive gradient shows constant velocity
True – Gradient represents velocity.
The resultant of two perpendicular forces is found using Pythagoras’ theorem
True – Vector addition applies.
If acceleration is zero, velocity must be zero
False – Velocity can be constant and non-zero.
An object thrown vertically upward experiences a constant upward force
False – Gravity acts downward throughout.
The normal reaction force acts perpendicular to the surface in contact
True – By definition.
The velocity of a particle is zero at its maximum height during vertical motion
True – Velocity changes sign here.
