force
What is work?
Energy transferred to or from an object by the application of force along a displacement.
What is the formula for force?
Mass x Acceleration = Force
What is the formula for speed?
Distance ÷ Time = Speed
What does a no speed graph show?
That the object has no speed or is stopped.
What is Sir Isaac Newton known for?
it is his formulation of the three laws of motion—the basic principles of modern physics—for which he is most famous.
What are joules?
A unit of energy transferred to an object when a force acts on that object.
What is a balanced force?
When two forces acting on an object are equal in size but act in the opposite directions.
What is the difference between velocity and acceleration?
Velocity of an object is the rate of change of its position with respect to a frame of reference and its function of time. Acceleration is is the rate of change of the velocity of an object with respect to time.
What is average speed?
The total path length travelled divided by the total time interval during which the motion has taken place.
What is constant velocity on a graph?
The position graph has a constant slope
How is a velocity graph shown?
A slope on a graph.
What is an unbalanced force?
When two forces acting on an object are not equal in size.
How do you calculate net force?
Net force is the sum of all forces acting on an object. The net force can be calculated using Newton's second law, which states that F = ma, where: F is the net force. m is the mass of the object.
What is an applied force?
A force that is applied to an object by a person or another object.
What is an example of newtons second law?
Pushing a car and a truck.
What is the difference between a constant acceleration graph and a acceleration graph?
What is net force?
The sum of the forces acting on an object.
What is friction?
The resistance that one surface or object encounters when moving over another.
What is newtons first law?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What does increasing acceleration look like one a graph?
Acceleration is represented by the slope, or steepness, of the graph line.
How is a constant speed graph shown?
A horizontal line shown on a graph.
What is the formula for work?
Force x Distance = Work
How do you find average speed?
Distance ÷ Time = Average speed
What is an example of newtons third law?
When two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
What is Emma's favorite color?
