Assertion: the numerical ratio of displacement to distance is equal to one or less than one.
Reason: displacement is a vector quantity and distance is a scalar quantity.

1) Assertion : A quick collision between two bodies is more violent than a slow collision, even when the initial and the final velocities are identical. Reason : The rate of change of momentum determines the force.

2) Assertion : While walking on ice, one should take small steps to avoid slipping.
Reason : This is because smaller steps ensure smaller friction

3)Assertion : If the net external force on the body is zero, then its acceleration is zero.
Reason : Acceleration does not depend on force

# data[].attributes.body
Assertion : Newton's laws can be applied to bigger bodies
Reason : During any kind of collision the centre of mass of the system is not accelerated.
Assertion: Inertia is the property by virtue of which the body is unable to change by itself the state of rest only.
Reason: The bodies do not change their state unless acted upon by an unbalanced external force
Assertion: Two balls of different masses are thrown vertically upward with same speed. They will pass through their point of projection in the downward direction with the same speed.
Reason: The maximum height and downward velocity attained at the point of projection are independent  of the mass of the ball

1. assertion : The forces of action and reaction always appear due to actual physical contact of two bodies
reason  : A particle can move only under the action of a force.
2. Assertion : If the net external force on the body is
zero, then its acceleration is zero.
Reason : Acceleration does not depend on force

1.Assertion: If displacement of a body is zero, the distance covered by it may not be zero. Reason: displacement is a vector quantity and distance is a scalar quantity.
2.Assertion: The speed of a body can be negative.
Reason: If the body is moving in opposite direction of positive motion, then its speed is negative.
3. Assertion : Linear momentum is conserved in both elastic and inelastic collisions.
Reason : Total energy is conserved in all collisions
4. Assertion : While walking on ice, one should take small steps to avoid slipping.
Reason : This is because smaller steps ensure smaller.

Assertion : A body can have acceleration even if its velocity is zero at a given instant of time.

Reason: A body is momentarily at rest when it reverses its direction of motion.

A) If both assertion and reason are true and the reason is the correct explanation of the assertion.

B)  If both assertion and reason are true but reason is not the correct explanation of the assertion.

C) If the assertion is true but reason is false.

D)If the assertion and reason both are false.

Assertion :A person working on a horizontal road with a load on his head does no work.

Reason: No work is said to be done, if directions of force and displacement of load are perpendicular to each other.

Assertion : The change in kinetic energy of a particle is equal to the work done on it by the net force.

Reason : Change in kinetic energy of a particle is equal to the work done only in case of a system of one particle.

1. Assertion: Two balls of different masses are thrown vertically upward with same speed. They will pass through their point of projection in the downward direction with the same speed.
Reason: The maximum height and downward velocity attained at the point of projection are independent  of the mass of the ball.

2. Assertion: Newton's second law of motion gives the measurement of force.
Reason: According to newton's second law of motion, force is directly proportional to the rate of change momentum.

# data[].attributes.body
Assertion: The forces of action and reaction always appear due to actual physical contact of two bodies.
Reason: A particle can move only under the action of a force.
Assertion : A quick collision between two bodies is more violent than a slow collision, even when the initial and the final velocities are identical. Reason : Because the rate of change of momentum which determines the force is greater in the first case.
Assertion : If the net external force on the body is zero, then its acceleration is zero. Reason : Acceleration does not depend on force.

1. Assertion : The acceleration due to gravity on the moon is one-sixth that on the earth.
Reason : The law of gravitation is the same on both the moon and the earth.

2. Assertion : The motion of a simple pendulum is simple harmonic for all angular displacement.
Reason : Motion of simple pendulum is independent of the angular displacement.

3. Assertion : Newton's laws can be applied to bigger bodies
Reason : During any kind of collision the centre of mass of the system is not accelerated.

4. Assertion : The change in kinetic energy of a particle is equal to the work done on it by the net force.
Reason : Change in kinetic energy of particle is equal to the work done only in case of a system of one particle.

5. Assertion : Newton’s third law applies to all types of
forces. e.g. gravitational, electric or magnetic forces
etc.
Reason : Newton’s third law of motion is applicable
only when bodies are in motion.

Reason: A body is momentarily at rest when it reverses it's direction of motion

2. Assertion: Inertia is the property by virtue of which the body is unable to change by itself the state of rest only.

1.Assertion: In a uniformly accelerated motion, acceleration the graph is straight line with positive slope.
Reason: Acceleration is rate of change of velocity.
2.Assertion : The displacement-time graph of a body moving with uniform acceleration is a straight line.
Reason : The displacement is proportional to time for uniformly accelerated motion.
3.

Assertion : The acceleration due to gravity on the moon is one-sixth that on the earth.
Reason : The law of gravitation is the same on both the moon and the earth.
