A person pushes a box. What is the push most likely to change?
What is the position?
This is a push or a pull.
What is a force?
A student throws a ball. What type of energy does a moving ball have ?
What is kinetic energy?
How do you calculate speed?
What is distance divided by time?
What is the definition of acceleration?
What is a change in velocity?
Energy cannot be destroyed. What can it do?
What is change forms?
If friction is present, what two things happen when an object is moving?
What is the object will slow down and heat is created?
Objects in motion stay in motion, objects at rest stay at -
What is rest?
Name two ways the velocity of an object can change.
What is increase/decrease in speed, or change direction?
An elephant and a lion are both moving with a speed of 5 m/s. Which animal has more kinetic energy?
What is the elephant?
Larger objects need more force to move them is an example of what law of motion?
What is the 2nd law?
What is the difference between speed and velocity?
What is speed is the measure of motion or how fast/slow you are moving and velocity is speed in a direction?
A 20kg rock accelerates to 5 m/s2. What is the magnitude of the force that caused this motion?
What is 100N?
This position is when the ball has the greatest amount of kinetic energy.
What is position D?
When the ball is at its highest point, it has potential energy. When the ball is falling towards the table, it has kinetic energy. It has the most kinetic energy at the very end of its descent when it is moving the fastest.
Name an example of potential energy.
Potential Energy: Stored energy that could cause change in the future.
Potential Energy Examples
What do you need to apply to an object to make it move?
What is an unbalanced force?
