## How increasing the time of impact would change the force required to stop the cart?

A force is applied to stop a moving shopping cart. How would increasing the time interval change the force required? The force required would be smaller because the amount of time that the force is applied is longer.

## What is the force of a moving object called?

The momentum of an object is proportional to its weight and speed. The more momentum it has, the more force it has.

## How does the force of friction for a sliding object vary with speed?

Frictional force is directly proportional to change in velocity. That is on increasing speed the friction also increases. Here the friction reaches to a top value that is a constant for a body on a surface. Beyond this point the friction remains constant on increasing the external force.

## What is two body collision?

In physics, an elastic collision is an encounter (collision) between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy.

## How is force reduced by increasing the time to stop?

Effects of rapid deceleration Crumple zones are designed to increase the time it takes for a car to stop totally. This reduces the force acting on a car. Seat belts and air bags are designed to increase the time it takes for passengers in a car to stop totally. This reduces the force acting on the passengers.

## What is the effect of increasing the force on the acceleration of the cart?

As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, if you double the force you double the acceleration.

## What is an example of a force can stop a moving object?

The stopping of a moving football by a goalkeeper demonstrates that a force can stop a moving object. 3)A cricket ball moving on the ground stops automatically after some time. The force of friction of ground stops the moving cricket ball. 4)The force of brakes can stop a moving car.

## What is an example of a force causing an object to stop moving?

The force stopping the object’s motion might be an obvious one – the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes friction.

## What is the force required to stop a moving object?

Any force applied for the right amount of time in the opposite direction to its motion will bring the object to a stop. For instance, the force of gravity acting on a rock thrown vertically upward.

## What is the weight in pounds of 1 Newton?

One Newton (kg. m/s^2) equals 0.225 pounds (lbs). In other words, there are 0.225 pounds per Newton. You can use this ratio to convert Newtons to pounds.

## What relationship does mass have with inertia?

Inertia is associated with an object’s mass. The larger the mass the larger the inertia. Both Galileo and Newton inferred that because of inertia, objects which are not being pushed or pulled, if initially motionless, will remain motionless.

## What is the simplest and most common type of force?

The force of gravity is the most basic and prevalent kind of force in physics.

## How does increasing impact time affect the force?

Increasing the time of the impact results in a decrease in the force. Therefore if t is increased, for a constant change in momentum, the force on the body is reduced.

## How changing the time of impact changes the force of impact?

The process of minimizing an impact force can be approached from the definition of the impulse of force: If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the time average of the impact force by the same factor.

## How does impact time affect force?

A large increase in collision time can mean decrease in impact force. This is essentially what an air bag in your car does. It increases the time over which it stops you and decreases the force.

## When the impact time is increased what happens to the force?

Observe that the greater the time over which the collision occurs, the smaller the force acting upon the object. Thus, to minimize the effect of the force on an object involved in a collision, the time must be increased.
