Force is measured using a unit called the Newton (N). One Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared (1 N = 1 kg × m/s²). Various instruments such as ...

The impact produced by objects depends on both their mass and velocity. Objects with greater mass or velocity tend to have more significant impacts. This is evident in the examples provided, where higher mass or velocity increases the potential harm ...

Examples include the difference in impact between a table tennis ball hitting a player (little to no harm) compared to a fast-moving cricket ball hitting a spectator (potential harm). Similarly, a stationary truck poses no threat, but a moving truck, ...

The acceleration of an object is directly proportional to the force applied to it. This means that the greater the force applied, the greater the acceleration experienced by the object, according to Newton’s second law of motion.

The first law of motion states that when an unbalanced external force acts on an object, its velocity changes, resulting in acceleration.
