OpenSciEd 8.1 - Lesson 6, Day 1 SAI

Front

What is total kinetic energy (KE)?

Back

Total kinetic energy (KE) is the sum of the kinetic energy of all the objects in a system.

Front

How does kinetic energy relate to motion?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What happens to kinetic energy during a collision?

Back

During a collision, kinetic energy can be transferred between objects, and some may be converted to other forms of energy.

Front

What is peak force in a collision?

Back

Peak force is the maximum force experienced during the moment of impact in a collision.

Front

When does peak force occur during a collision?

Back

Peak force occurs at the moment of contact between colliding objects.

Front

How does the mass of an object affect its kinetic energy?

Back

Kinetic energy increases with the mass of the object, as KE = 1/2 mv².

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What is the significance of a soccer ball's energy in a collision?

Back

The energy from a soccer ball can influence the peak forces experienced during a collision.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, total kinetic energy is conserved; in inelastic collisions, some kinetic energy is transformed into other forms of energy.

Front

What is the role of momentum in collisions?

Back

Momentum is conserved in collisions, meaning the total momentum before the collision equals the total momentum after.
