Unit 4 Force and motion, 6th grade

Front

What is radiant energy?

Back

Energy from light, which includes UV Rays, infrared radiation, and microwaves. Examples include sunlight, neon lights, and x-rays.

Front

What is acceleration?

Back

The rate of change in an object's velocity.

Front

What is friction?

Back

A force between an object and the surface it is moving over; it causes a moving object to slow down when it touches another object.

Front

What is mechanical energy?

Back

Energy from the motion of an object (kinetic) or from the position of an object (potential). Examples include a turning gear, a bowling ball on a shelf, sound, and wind.

Front

What is kinetic energy?

Back

The energy that an object has because it is moving.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state. For example, a book on a shelf has potential energy.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is a balanced force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.
