momentum

• Momentum is defined as the product of an object's mass and its velocity.
• when an object has more momentum, it will have greater force when colliding with another object
• the formula for momentum is p=mv
• momentum is the product of mass and velocity
• Momentum conservation is applicable to both elastic and inelastic collisions.
• The impulse-momentum theorem states that the change in momentum of an object is equal to the impulse applied to it.
• The SI unit for momentum is kg m/s, with larger objects having greater momenta at the same speed.
• If one object has more momentum than another, it will have a greater effect when they collide.
• A car traveling at high speeds can cause significant damage due to its large mass and momentum.
• When two objects collide, the total momentum of the system remains constant unless acted on by external forces.
• In a head-on collision between two cars, the car with the higher momentum (mass times velocity) will experience a smaller change in velocity compared to the other car.
• In a collision between two objects, if the initial momentum of the first object is greater than the second object's initial momentum, then the final velocity of the first object must be greater than the second object's final velocity.
• In a collision between two objects, if the initial momentum of the first object is less than or equal to the second object's initial momentum, then the final velocity of the first object must be less than or equal to the second object's final velocity.
• During this time, the ball's momentum changes direction without changing magnitude.
• When a ball bounces off a wall or floor, there is no net external force acting on it during the brief period of contact.
• In a collision between two cars, the total momentum remains constant but may be transferred from one vehicle to the other.
