Energy and Speed

Front

What is energy?

Back

Energy is the ability to do work or cause change. It can exist in different forms, such as kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is speed?

Back

Speed is the rate at which an object moves. It is calculated by dividing the distance traveled by the time taken.

Front

How can energy affect speed?

Back

More energy can make an object move faster. For example, a toy car with more energy will travel faster down a ramp.

Front

What happens when two objects have different amounts of energy?

Back

The object with more energy will usually move faster than the one with less energy.

Front

What is the relationship between mass and speed?

Back

Generally, if two objects have the same amount of energy, the one with less mass will move faster.

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 stored energy that has the potential to do work. For example, a ball at the top of a hill has potential energy.

Front

How can we measure speed?

Back

Speed can be measured by calculating the distance traveled over a specific time period, usually in units like meters per second (m/s).

Front

What is the effect of a ramp's height on a toy car's speed?

Back

A higher ramp gives the car more potential energy, which can convert to more kinetic energy, making the car go faster.

Front

What is the formula for calculating speed?

Back

Speed = Distance ÷ Time.
