Misconception NGM037:

An object always gains energy as it moves. For example, the height that a pendulum reaches after it is released is greater than its starting height because it gains energy as it swings (Loverude, 2004).

NG084002

Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, the ball will only move to a height equal to the height from which it started. It will not be able to go over a hill that is higher than the point from which it started.

A roller skater, who coasts down one hill and up another hill that is the same height as the first hill, will not have enough energy to reach the top of the second hill because some of her motion energy is transformed into thermal energy.

When two balls collide, a small amount of energy was transferred to the environment as thermal energy.

NG071002

Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, the ball will move down the track and then up to a point equal to the height from which it started.

Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, the ball will move down the track and then up to a point equal to the height from which it started.

The total amount of energy in a system remains the same unless energy enters or leaves the system.

As a boy pushes a girl on a swing, the boy’s energy decreases, and the girl’s energy increases because the boy transferred some of his energy to the girl when he pushed her.

NG085003

Assuming that no energy is transferred between a ball and the curved track it is moving in, or between the ball and the air around it, the ball will not have enough energy to go over a hill that is higher than the height from which it started because the total energy of the system has to remain the same.

NG069005

In a situation involving two slides, and assuming no energy transfer between the slides and the students sliding on them or between the students and the air around them, two students of the same mass sliding down differently shaped slides will have the same speed at the bottom of the slides because the only source of motion energy is the change in gravitational potential energy, and both students experience the same change in gravitational potential energy.

Assuming no energy transfer between a roller coaster car and the track it is moving in or between the car and the air around it, all of the hills that a roller coaster car can get over must be lower than the height of the starting point.
