For every action there is an equal and opposite reaction.
What is Newton's 3rd Law?
In order for an object to begin to move, stop moving, or change direction, which of the following must be present?
What is an unbalanced force?
An object's acceleration (change in speed) depends on the mass of the object and the amount of force applied on it.
What does Newton's second law of motion state?
True or False
In order to calculate speed, you need to know distance and area.
What is FALSE? (Time)
If there is more mass in an object, there will be greater between the objects being pressed on.
If greater the mass of an object, the greater friction there is between the object and the surface the object is pressing on.
Another name for the first law of motion.
What is Law of Inertia?
An object at rest __________ until a force acts on it.
What is remains at rest?
A ___ is a push or a pull.
What is a force?
The forces that makes a rolling ball slow down and stop is .
What are friction and gravity?
Relationship between Force, Mass and acceleration.
What Law?
What is Newton's 2nd Law of Motion?
The tendency of an object to remain at rest or in motion is ______________.
What is inertia?
Forces that delete the effect of each other are called_________ forces.
What are balanced forces?
When a baseball is hit, the ball pushes on the bat and the bat pushes on the ball.
What is a Newton's 3rd Law?
A passenger not wearing a safety belt hits the windscreen of a car in a head-on collision. This is an illustration of________
What is Newton's 1st Law of Motion
True or False Your weight is constant everywhere in the universe?
False. Your weight does not change ANYWHERE in the universe.
An object in motion stays in motion unless a force acts on it.
What does Newton's first law of motion state?
Speed and direction
What is velocity?
In order for an object to begin to move, stop moving, or change direction, which of the following must be present?
What is an unbalanced force?
Acceleration is calculated by dividing the force exerted on an object by the mass of the object, and that when a force acts on an object, its acceleration is in the same direction as the force.
What is Newton's second law of motion?
The air in a balloon exits in one direction and the balloon travels in the opposite direction.
What is Newton's 3rd Law?
The force resulting from the pull of Earth on an object is _______________.
What is gravity?
Metric unit for length.
What is meter?
Two forces working in opposite directions, each with a force of 20 N, are ____________.
What is a balanced.
True or False Newton's law of universal gravitation states that an object in motion will stay in motion unless acted by a force?
True Newton's law of universal gravitation states-that an object in motion will remain in motion until a force is acted upon it.
is required to overcome gravity.
What overcomes gravity, mass is required to overcome the gravitational pull.
