Laws of Motion
Physics ⇒ Mechanics
Laws of Motion starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Laws of Motion.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A 10 kg object is at rest. What is the net force required to accelerate it to 2 m/s²?
A 2 kg object is dropped from rest. What is the force acting on it due to gravity? (Take g = 9.8 m/s²)
A 3 kg object is moving with a velocity of 6 m/s. If a force of 9 N acts in the direction of motion for 2 seconds, what will be its final velocity?
A 4 kg object is moving at 5 m/s. If a force of 8 N acts opposite to its motion, how long will it take to come to rest?
A 5 kg object is acted upon by a net force of 20 N. What is its acceleration?
A block of mass 2 kg is sliding on a frictionless surface with a velocity of 3 m/s. What is the net force acting on the block?
A car of mass 1000 kg accelerates from rest to 20 m/s in 10 seconds. What is the average force applied?
A force of 15 N is applied to a 3 kg object at rest on a frictionless surface. What will be its velocity after 4 seconds?
A force of 50 N is applied to a 10 kg box on a horizontal surface. If the coefficient of kinetic friction is 0.2, what is the acceleration of the box? (Take g = 10 m/s²)
