Total questions: 10
Worksheet time: 5mins
What is the SI unit of length?
centimeter
meter
kilometer
millimeter
How is acceleration defined in physics?
Acceleration is the rate of change of velocity per unit time.
Acceleration is the speed of an object at a given moment.
Acceleration is the distance traveled over time.
Acceleration is the force applied to an object.
What unit is used to measure force?
Pascal
Joule
Watt
Newton
If an object is accelerating, what can be said about the forces acting on it?
There is no force acting on it.
There is a net force acting on it.
The forces are balanced.
The object is at rest.
What is the formula for calculating acceleration?
a = v_f + v_i
a = v_i / t
a = (v_f * v_i) + t
a = (v_f - v_i) / t
What is the unit of measurement for mass in the SI system?
gram
liter
pound
kilogram
How does mass affect the acceleration of an object when a force is applied?
Greater mass always results in greater acceleration for the same force.
Mass has no effect on acceleration when a force is applied.
Mass inversely affects acceleration; greater mass results in less acceleration for the same force.
Acceleration is independent of the mass of the object.
What is the relationship between force, mass, and acceleration according to Newton's second law?
F = m * a
F = a - m
F = m / a
F = m + a
What is the difference between speed and velocity?
Speed is scalar; velocity is vector (includes direction).
Speed can be negative, while velocity cannot.
Velocity measures distance only, not direction.
Speed is always greater than velocity.
How do you convert kilometers per hour to meters per second?
Divide the speed in km/h by 3.6.
Multiply the speed in km/h by 3.6.
Add 3.6 to the speed in km/h.
Convert km/h to miles per hour first.
