Forces
The definition of a force
What is a push or a pull?
the amount of matter in an object.
What is mass?
The way to mathematically find force is through the formula...
newton has how many laws of motion
What is 3 laws of motion?
This is what happens to the acceleration of an object if its mass remains unchanged while the net force acting on it is cut in half.
What is cut in half?
2 people pushing on a desk that has a Net force of 10 N straight. What type of force is this?
What is an unbalanced force?
A force that pulls objects toward each other.
What is gravity?
The rate at which velocity changes over time...
What is acceleration
A smaller object needs less ___ to achieve the same acceleration that the larger object has
What is force.
If a force of 10N occurs on a mass of 2kg, what must be the acceleration?
What is 5m/s2
2 people arm wrestling, there is a zero net force and each is equal strength. What type of force is this?
What is a balanced force?
2 factors that affect gravity.
What is mass and distance?
A=? when f=18N and m= 3kg
What is 6m/s2
Newton's second law states
What is the acceleration depends on the mass and on the net force acting on the object? It can also be written as f=ma
Mrs. Wallace is going down the sidewalk on her skateboard; Mrs. Hill decides to get on too. What will Mrs. Wallace have to do to keep the skateboard moving at the same velocity?
What is "push with more force"?
2 or more forces acting on your sled
What is gravity, friction, and air resistance?
On which planet will you weigh the most on?
What is Jupiter?
An object's acceleration ___ as its mass increases
What is decreases
is the resistance to change
What is inertia?
Two marbles of different masses are released at the top of a ramp and roll down the ramp. The student measures the distance each marble travels. The procedure is repeated three times and the average distance traveled by each marble is calculated. Which of the following is the independent variable(cause) in the investigation?
What is the marble mass?
a box is pulled 4N to the right and pulled 6N and 2 N to the left. What is the net force
What is a net force of 4 N
Solve for mass? What formula do you need to use?
What is m=f/a?
F=? when a=5.8m/s2 and m= 19.4kg
What is 112.52N
If I take a feather and a 200 lbs person into space, will they weigh the same and will they have the same mass?
The feather and person will weight same because they will be weightless but their masses will be different.
Which would have a greater acceleration, a small car or a large car, if the same force is applied?
What is "a small car"?
