4th Grade Collisions Review

Front

What is energy?

Back

Energy is the ability to make things happen or to do work. It can be found in different forms such as light, heat, and motion.

Front

What is a variable in an experiment?

Back

A variable is a factor that can change in an experiment. To make a fair test, you should change only one variable at a time.

Front

What happens when energy is transferred?

Back

When energy is transferred, it can cause objects to move or change. For example, energy from a moving ball can knock down bowling pins.

Front

What is a collision?

Back

A collision is when one object runs into another object. It can happen in many ways, like a car crash or a ball hitting a wall.

Front

What is the relationship between speed and energy?

Back

As an object moves faster, it has more energy to transfer. Faster objects can do more work.

Front

Can you hold energy in your hand?

Back

No, you cannot hold energy in your hand. Energy is not a physical object; it is a property that can cause changes.

Front

What is matter?

Back

Matter is anything that has mass and takes up space. Everything around us is made of matter.

Front

What is the importance of a fair test in an experiment?

Back

A fair test ensures that the results are valid and reliable. It allows scientists to understand the effect of the variable being tested.

Front

What are some forms of energy?

Back

Some forms of energy include kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), and light energy.

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.
