Energy
What is defined as ' the ability to do work'?
Energy
What is energy in motion
Kinetic energy
What is an energy transfer?
Energy is moved from one object to another.
Define speed
The speed of an object does not depend on the direction in which it is travelling.
Who is Newton?
Isaac Newton
True or false, all things possess energy, even if they are not moving.
True
What is stored energy
Potential energy
What is an energy transformation?
Energy undergoing a change in form.
Define velocity
The velocity of an object is the speed and direction in which it is moving.
What is Newton's first law?
Objects in motion tend to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force.
True or false, Energy can be transferred to another object.
True
What type of energy is defined as 'kinetic energy with the ability to make types of light visible to human eyes'
Light energy
List the energy transfers and transformations involved in kicking a soccer ball.
Teacher judgement
How do you calculate the speed an object is travelling?
What is the formula?
speed= distance/time
What is Newtons second law?
Force equals mass times acceleration (F = mxa)
Can energy be stored.
Yes
What type of energy is defined as 'the form of potential energy stored within atoms and molecules'
Chemical energy.
List the wasted and useful energy in bouncing a ball.
Useful: EPE, kinetic and potential
Wasted: Thermal and sound
A train takes 100 seconds to travel 1500m. What is its speed?
15m/s
What is Newton's third law?
For every action there is an equal and opposite reaction.
Identify the type of energy required to turn on a light.
Thermal, light, electrical.
List the types of energy involved with bouncing a ball?
Elastic potential energy, kinetic energy, potential energy, thermal and sound energy.
Define the Law of conservation of energy.
Energy cannot be made or lost. However, energy can be transformed or transferred.
A car takes 150 seconds to travel 500m. What is its speed?
3.33m/s
What law is "no force=no movement and force=movement" an example of?
Newton's first law
