AC-HPAT 2024/2025 PHYSICS EXAM PRACTICE QUESTIONS
100% CORRECTLY SOLVED ANSWERS.



1) What is Newton's first law? -- Answer ✔✔ An object at rest stays at rest and an
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _




object in motion stays in motion with the same speed and in the same direction
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _




unless acted upon by an unbalanced force.
_ _ _ _ _ _




2) What are scalar and vector quantities? Examples. -- Answer ✔✔ Scalars are
_ _ _ _ _ _ _ _ _ _ _ _




quantities that only have magnitude (or size), while vectors have both magnitude
_ _ _ _ _ _ _ _ _ _ _ _




and direction.
_




Scalar: time, area, volume, temperature, and mass.
_ _ _ _ _ _




Vector: displacement, velocity, force, and acceleration.
_ _ _ _ _




3) Difference between distance and displacement? How to calculate? -- Answer ✔✔
_ _ _ _ _ _ _ _ _ _ _




Distance is the length of the path taken and is usually measured in metres or
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _




kilometres.

4) Displacement is a vector quantity that represents the change in position in a given
_ _ _ _ _ _ _ _ _ _ _ _ _ _




direction. _




Delta D = D2-D1 _ _ _




5) What is velocity and how do you find it? -- Answer ✔✔ The velocity of an object
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _




is the rate at which the position is changing with respect to time.
_ _ _ _ _ _ _ _ _ _ _ _




V=(displacement)/time

6) What is acceleration and how do you find it? -- Answer ✔✔ Acceleration is the
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _




rate of change of velocity with respect to time.
_ _ _ _ _ _ _ _




a = delta (velocity) / delta (time)
