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.

A 1 kg ball moving at 10 m/s hits a wall and bounces back with the same speed. What is the change in momentum?
A 10 kg object is at rest. What is its momentum?
A 2 kg object accelerates at 3 m/s². What is the force acting on it?
A 2 kg object moving at 5 m/s is stopped in 1 second. What is the force required to stop it?
A 3 kg object is initially at rest. If a force of 9 N is applied for 2 seconds, what is its final velocity?
A 4 kg object is moving at 3 m/s. What is its momentum?
A 5 kg object is moving with a velocity of 4 m/s. What is its momentum?
A 6 kg object is moving at 2 m/s. What is its momentum?
A ball is thrown vertically upwards. What is the direction of the net force acting on it while it is rising?
A car of mass 1000 kg is moving with a velocity of 20 m/s. Calculate its momentum.
A force acts on a 0.5 kg object and changes its velocity from 2 m/s to 6 m/s in 2 seconds. What is the magnitude of the force?
A force of 10 N is applied to a mass of 2 kg. What is the acceleration produced?
A force of 8 N is applied to a 4 kg object. What is the acceleration produced?
Define momentum.
If a force of 15 N acts on a body and produces an acceleration of 5 m/s², what is the mass of the body?
If a moving object comes to rest, what can you say about the net force acting on it during this process?
If the mass of an object is doubled while keeping the force constant, what happens to the acceleration?
If the net force acting on an object is zero, what can you say about its motion?
