Front

What is the direction of movement for a wooden block attached to two spring scales when the force is applied to the right?

Back

The wooden block will move to the right.

Front

What type of energy does Ball A have when it is resting near the edge of a shelf compared to Ball B on the ground?

Back

Ball A has more potential energy than Ball B.

Front

What type of change occurs when two or more substances combine to form a new substance?

Back

Chemical change.

Front

What type of change occurs when two or more substances combine but no new substance is formed?

Back

Physical change.

Front

At which location does a skateboarder have the most kinetic energy and the least potential energy when moving from location 1 to location 4?

Back

At location 2.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the formula for calculating potential energy?

Back

Potential Energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What happens to the potential energy of an object as it falls?

Back

The potential energy decreases while kinetic energy increases.
