    Default momentum and impulse

    "That's dangerous, not only for the driver, but for everyone else on the road. The brake system is designed for a load of 21 tones. When the truck is eight or nine tones overloaded, the momentum doesn't let you stop unless you really stand on the brakes."

    Hi,

    I would like to know if I could use “impulse” instead of ”momentum” in this sentence.

    I also wonder if “momentum” is an informal word. In the negative case, which word should I use casually, please?

    Thanks.

    Momentum is the correct word, meaning the quantity of motion of a moving body, equal to the product of its mass and velocity.

    Impulse is not an alternative in this context. There is no "informal" word that can replace momentum.

    Momentum is the impetus of a moving body.It is the product of mass and velocity.
    Impulse is the effect of momentum in a very short period of time .
    So momentum is correct here.

    RonBee :Yes - but you've won ground with 'program'. The only time we see 'programme' any more is referring to the flyer at a theatre performance. It's all 'TV programs' here now.
