Answer 2

Assertion: The Force required to accelerate a mass in two perpendicular directions is never the same.

Reason: The presence of g will not influence the acceleration.

This Assertion is true but the reason is false.

• Forcetime = mv = Momentum = Impulse

      When a body reverses direction, it will be at rest for a brief duration. When a body is in equilibrium, it has the least amount of potential energy and is not subjected to any external forces.

• Because force would be a vector field, its direction will produce distinct force quantities. The influence of force on motion is depending on the product of the object's mass (i.e. momentum). If a constant force is given for a set amount of time to two components of distinct masses that are initially at rest, the lighter body will accelerate faster than the larger body.
• Observations demonstrate that at the conclusion of such time interval, each body has the same momentum. As a result, for various bodies, the same force applied at the same time induces the same change in momentum. It is a crucial bit of information concerning Newton's second 2nd motion law.
• The vector nature of momentum has not been obvious in the earlier measurements. Both momentum and change in momentum have the same direction in the cases thus far.
