Vocabulary
What is the term for: the force a planet or other body uses to draw objects towards its center.
Gravity
How many laws of motion are there?
3
A ball is kicked across a field and pulled down to earth then becomes still. What force is this an example of?
Force of gravity
A child pushes a toy car and lets it go. It moves across the floor and eventually stops. The force responsible for stopping the car is:
Friction
What is the term for: A push or a pull
Force
Who are the Laws of Motion named after?
Sir Isaac Newton
A ball is kicked across a field and caught by someone. What force is this an example of?
An applied force.
An apple on a tree falls to the ground. The force responsible for pulling the apple to the ground is:
Gravity
What is the term for: A force applied to an object by a person or a different object.
applied force
For every action there is an equal and opposite reaction. = Which law of motion?
Newtons Third Law of Motion
A ball is kicked across a field and it lands on the grass and rolls to a stop. What force makes it stop rolling?
Force from friction
A baseball sits at rest on a tee. Once a batter hits the ball with a bat, the ball is set into motion. This example helps to show Newton’s First Law of motion since
An object at rest stays at rest unless another force acts upon it to make it move.
What is the term for: the change in an object’s position over time.
Motion
An objects motion remains constant until a force is applied to the object. = What law of motion is this?
Newton's First Law of Motion
Kicking a soccer ball requires [More or Less] force to move than kicking a bowling bowl.
Less
A shopping cart is partially filled with groceries. If more groceries are added to the cart, what would be needed to increase the motion of the shopping cart?
Applying more force to the shopping cart.
What is the term for: a force that acts in the opposite direction of the motion of an object.
Friction
The greater the mass of an object, the more force need to make it move. = Which Law of Motion is this?
Newton's Second Law of Motiom.
A basketball and bowling bowl collide; which ball will be pushed back farther?
basketball
Two figure skaters start their performance with their hands touching as shown by the image. When the skaters use the action of pushing their hands against one another, they are sent backwards in opposite directions from one another. This action led to an equal and opposite reaction that demonstrates:
Newton’s Third Law of Motion
