Impulse Solution

Follow our step by step solution on how to calculate Impulse?

FIRST Step Consider the formula

i = F \cdot t

Next Step Substitute values of Variables

∴

i = 2.5N \cdot 5s

Next Step Prepare to Evaluate

∴

i = 2.5 \cdot 5

LAST Step Evaluate

∴

i = 12.5kg*m/s

Variables

Impulse

Impulse is the change in momentum of an object when a force is applied to it for a short period of time, resulting in its motion.

Symbol: i

Measurement: MomentumUnit: kg*m/s

Note: Value can be positive or negative.

Formulas to find Impulse

Force

Force is a push or pull that causes an object to change its motion or shape, resulting in acceleration or deceleration.

Symbol: F

Measurement: ForceUnit: N

Note: Value can be positive or negative.

Time Taken to Travel

Time Taken to Travel is the duration required for an object to cover a certain distance under the influence of kinetic forces.

Symbol: t

Measurement: TimeUnit: s

Note: Value should be greater than 0.

How to Evaluate Impulse?

Impulse evaluator uses Impulse = Force*Time Taken to Travel to evaluate the Impulse, Impulse formula is defined as the change in momentum of an object that occurs when a force is applied over a specific time period, resulting in a sudden increase or decrease in the object's velocity, often observed in collisions or explosions. Impulse is denoted by i symbol.

How to evaluate Impulse using this online evaluator? To use this online evaluator for Impulse, enter Force (F) & Time Taken to Travel (t) and hit the calculate button.

FAQs on Impulse

What is the formula to find Impulse?

The formula of Impulse is expressed as Impulse = Force*Time Taken to Travel. Here is an example- 12.5 = 2.5*5.

How to calculate Impulse?

With Force (F) & Time Taken to Travel (t) we can find Impulse using the formula - Impulse = Force*Time Taken to Travel.

Can the Impulse be negative?

Yes, the Impulse, measured in Momentum can be negative.

Which unit is used to measure Impulse?

Impulse is usually measured using the Kilogram Meter per Second[kg*m/s] for Momentum. Gram Centimeter per Second[kg*m/s], Dyne Hour[kg*m/s], Kilonewton Minute[kg*m/s] are the few other units in which Impulse can be measured.
