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?
What happens to speed as friction decreases?
What is increases
You want to conduct an experiment with a simple machine. First, you make an inclined plane by placing a book under one end of a ruler. Next, you will place a marble in the groove of the ruler at the top of the incline. Then, you will release the marble and measure the distance it travels. How could you increase the distance traveled by the marble?
What is increasing the height of the book?
What is the definition of acceleration?
What is a change in speed/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?
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?
Why do larger objects need more force to move them?
What is more mass=more force needed
What does it mean if you have balanced forces?
What is there is no motion/0 net force
What is gravity, force from ground, force from either direction?
This position is when the ball has the greatest amount of kinetic energy.
What is position D?
What do you need to apply to an object to make it move?
What is an unbalanced force?
