Amazing Unit 3 flashcardziz

Front

What is momentum?

Back

Momentum (p) is the product of an object's mass (m) and its velocity (v), expressed as p = mv.

Front

How does momentum change with speed?

Back

If two objects have the same mass, the object with the higher speed will have greater momentum.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force (F) x Time (t).

Front

What happens to force if impulse stays the same and time is tripled?

Back

If impulse stays the same and time is tripled, the force must be cut to a third (F = Impulse/t).

Front

What is the relationship between mass and force in a collision?

Back

In a collision, the object with greater mass will generally exert a greater force if both objects experience the same acceleration.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved, but kinetic energy is not.

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

Front

What is the effect of a bouncy ball compared to a clay ball when thrown at a wall?

Back

A bouncy ball will exert a greater impulse on the wall because it rebounds, while the clay ball sticks and does not transfer momentum back.

Front

How do you calculate impulse?

Back

Impulse can be calculated using the formula Impulse = Change in momentum = Final momentum - Initial momentum.

Front

What is the formula for calculating momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.
