100

A visual representation of all the forces acting on an object.

What is free body diagram

100

The total force acting on an object.

What is the net force

100

Newton's First Law of Motion

What is an object at rest stays at rest, an object in motion stays in motion, unless acted upon by an unbalanced force

100

Inertia depends only on this.

What is mass

100

The force that pulls objects to the Earth

What is the gravitational force

200

Sign of forces pointing up or to the right.

What is positive

200

Balanced forces result in this type of motion.

What is stationary or constant velocity.

200

Newton's Second Law

What is F = ma or the relationship between force, mass, and acceleration

200

 A soccer ball rolling across the ground after being kicked is an example of this law.

What is Newton's First Law

200

The pulling force from a rope

What is tension

300

Sign of forces pointing down or left

What is negative

300

The net force of air resistance 6 N up and the gravitational force 10 N down.

What is 4 N down or -4 N.

300

Newton's Third Law

For every action, there is an equal and opposite reaction

300

Tim pushes on the wall. The wall pushes back on Tim with this amount of force.

What is equal

300

The force that results from an external action (pushing, pulling, kicking...)

What is applied force

400

On a free body diagram, the gravitational force points in this direction.

What is down

400

The net force of a cart that has a normal force of 6 N up, a gravitational force of 6 N down, an applied force of 6 N left, a frictional force of 5 N right.

What is 1 N left or -1 N.

400

The tendency of an object to resist a change in motion

What is inertia

400

A car with a mass of 1100 kg accelerates at 2 m/s/s. The net force acting on the car is this.

What is 2200 N

400

The force that opposes the motion of an object on a surface

What is friction

500

On a free body diagram, the length of the arrow corresponds to this.

What is the magnitude of the force.

500

Unbalanced forces result in this type of motion.

What is accelerating.

500

A 5 kg block is being pushed across a table with a net force of 10 N. The acceleration of the block is this.

What is 2 m/s/s

500

Sam travels to the moon which has an acceleration due to gravity of 1.6 m/s/s. This is how much Sam would weigh on the moon if he had a mass of 65 kg.

What is 104 N

500

The force that is perpendicular to the surface that an object is on
