FOSS Inv. 4: Energy Transfer

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to move in a certain direction. They occur when two or more forces acting on an object are not equal in size and direction.

Front

What is mechanical energy?

Back

Mechanical energy is the energy that an object has due to its motion (kinetic energy) and its position (potential energy). All living things and machines use mechanical energy to do work.

Front

Which position causes a ball to roll the slowest?

Back

Position 1 causes the ball to roll the slowest and have the least kinetic energy.

Front

Which position has the most potential energy?

Back

Position 4 has the most potential energy because it is at the highest point.

Front

What is energy transfer?

Back

Energy transfer is the change in speed, position, and direction when objects collide. It explains how energy moves from one object to another.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling objects down toward its center.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or condition. For example, a ball at the top of a ramp has potential energy.

Front

What happens when two objects collide?

Back

When two objects collide, their motion changes due to energy transfer, which can result in a change in speed, direction, or both.

Front

What is the relationship between height and potential energy?

Back

The higher an object is positioned, the more potential energy it has. This is because it has the potential to fall and convert that energy into kinetic energy.
