OpenSciEd 8.1 Soccer Assessment Review

Front

What is the elastic limit?

Back

The most force before an object deforms permanently.

Front

What causes changes in motion during a collision?

Back

Transfer of kinetic energy.

Front

What happens to a baseball bat when a baseball hits it with a force of 500 Newtons, given its elastic limit is 530 Newtons?

Back

The bat bends, but isn't permanently deformed.

Front

If a moving object collides with a stationary object, what can be said about the peak force?

Back

The peak force will be the same on both objects.

Front

How does speed affect the kinetic energy of objects with the same mass?

Back

Faster objects have more kinetic energy.

Front

Define kinetic energy.

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between mass and kinetic energy?

Back

For a given speed, an object with more mass has more kinetic energy.

Front

What happens to the kinetic energy of an object if its speed doubles?

Back

The kinetic energy increases by a factor of four.

Front

What is a Newton?

Back

A unit of force in the International System of Units (SI), defined as the force required to accelerate a 1 kg mass by 1 m/s².
