# Which case has the greatest impulse?

The impulse required is greatest when the ball is caught and then thrown back because the impulse required equals the change in momentum.

## What is the formula for solving impulse?

The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.

## What is impulse formula Class 11?

Impulse can also be articulated as the rate of change of momentum. J=m×v. Where, Mass of the body is given as m. The velocity with which the body is moving is given as v.

## How do you find impulse in AP Physics?

Impulse is defined as the average force exerted by an object times the amount of total time elapsed. Impulse is represented by J = Average Force * time. The impulse can be found by finding the area underneath a force vs. time graph.

## What are 3 examples of impulse?

• Footballer. When a football player kicks a ball suddenly with force, the ball shoots away.
• Golf. When the golf ball is hit by the player, it receives a sudden change in momentum.
• Tennis.
• Martial Art.
• Pile driver.
• Pestle and Mortar.
• Egg Carton.
• Dropping a Ball.

## Can an impulse be negative?

Impulse is a vector, so a negative impulse means the net force is in the negative direction. Likewise, a positive impulse means the net force is in the positive direction.

## Is impulse the change in momentum?

From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. It is equal to the change in momentum.

## How do you find impulse without time?

You can type the initial and final momentum values into our calculator to find the impulse directly from the impulse formula J = Δp . You can also enter the values of mass and velocity change of an object to calculate the impulse from the equation J = mΔv .

## What is the SI unit of impulse?

The SI unit of impulse is Newton-seconds (Ns) or kg m/s.

## Is impulse a force?

Impulse is a vector quantity like force and it also has direction.

## What is impulse equal to?

Impulse is the measure of the total effect of a force. Mathematically, impulse can be represented as, Impulse = average force × time. The unit of impulse is kg ms – 1 or N s .

## What is impulse-momentum theorem Class 11?

The impulse-momentum theorem states that the impulse applied to an object is equal to the change in its momentum. It proves that the change in momentum of an object depends not only on the amount of force applied but also on the duration of force applied.

## What are possible formulas for impulse check all that apply?

• Impulse = Force * time = force * Delta t. Delta t = t^final – t^initial.
• Impulse = Delta p = p^final – p^initial.

## What are real life applications of impulse force?

• Most famous and commonly quoted – Batsman hitting the ball while playing cricket.
• Kick starting a bike.
• Similar to the first one – Whle playing Carroms, the striker hits the coin for a very short time but sends it to the pocket.
• Hitting a gong with the stick sets it ringing loudly.

## What is impulse in real life?

You use the concept of impulse in your everyday life without even realising it, for instance, when you hit a punching bag or kick a ball. So, The concept involves a change in the object’s momentum when force is introduced for a specific time.

## How do airbags affect impulse?

Air bags in cars are designed with impulse, or momentum change principles. When a driver gets into an accident their momentum carries them forward into the steering wheel. By putting an airbag in the car, a smaller force is exerted over a longer period of time to change the momentum of the driver to a stop.

## What is impulse momentum theorem?

The impulse-momentum theorem states that the impulse applied to an object will be equal to the change in its momentum. Δ→tF=m(vf)−m(vi) Notice that we have calculated the change in momentum as the initial momentum (mivi) subtracted from the final momentum (mfvf).

## Can physics force be negative?

Magnitude of a force is never negative but direction can be negative that is opposite direction. When a body goes on a surface, the friction force between the body and the surface is in a direction reverse to the body’s motion, so the work performed by the friction force is negative.

## How do you find impulse with mass and time?

Calculator Use The Impulse Momentum Calculator uses the formula FΔt = mΔv, or force F multiplied by the change in time Δt equals mass m times the change in velocity Δv.

## Can the impulse of a force be zero?

The impulse of a force can be zero, if the net force acting on the particle during that time interval is constant. Since the force is constant (both magnitude and direction), so change in momentum produced by the force will be zero. Therefore impulse of the force will be zero.

## Does impulse increase with time?

Impulse of Force It is equal to the change of momentum of an object that isn’t changing mass. This is a useful concept when you are studying impact forces. If you increase the time over which the change of force happens, the impact force also decreases.

## Is velocity a vector?

Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.

## What does impulse depend on?

So, the impulse exerted on an object depends directly on both how much force is applied and for how long the force is applied. Impulse is the product of the force and the time. Impulse = (force)(time) = Ft.
