45 True/False questions

downward → Which has a bigger mass: Earth/Person whilst jumping?

4 m/s² → A 2kg object experiences a net force of 8N. What is the object's acceleration?

gravitational, electromagnetic → When someone jumps up, this pulls them back down.

Free Body Diagram → Weight equation

Normal Force → Friction opposes this.

tension, applied, normal, friction → This is the ratio of the force of friction on an object to the normal force acting on the object.

Air Resistance → Example of an "outside force" that would stop an object

Neither → The measure of a gravitational force acting on an object.

50 N → What is the gravitational force acting on a 5 kg object?

amount of force to accelerate 1kg of mass at 1 m/s² → What is a Newton?

No → An object is traveling at a constant 4m/s and moves left. Is it in equilibrium?

force of book on table → Action/Reaction pairs: What is the Action pair in a physics book on a table?

Weight → Which has a bigger force: Earth/Person whilst jumping?

9.81 m/s² → The "g" in the weight equation is this on earth.

Inertia → This friction is the resistive force on an object in motion).

Newton's First Law → For every action there is an equal and opposite reaction.

Forces → The arrows in FBDs represent these and go out from an object.

0N, 0 m/s² → An object is in equilibrium if it's net force equals this and its acceleration equals this.

Distance → Field forces act over a....

not moving, constant velocity → If an object is doing this or traveling at a this, it is in equilibrium.

force of table on book → Action/Reaction pairs: What is the Reaction pair in a physics book on a table?

Newton's Second Law → For every action there is an equal and opposite reaction.

Coefficients of Friction → This is the ratio of the force of friction on an object to the normal force acting on the object.

Fnet=ma → An objects resistance to change its motion

Parallel to surface, direction of motion → This is the ratio of the force of friction on an object to the normal force acting on the object.

1N = 1 kg * (m/s²) → Newton is equal to.

mass → Newton's first law is directly related to this.

kinetic → This friction is the resistive force on an object in motion).

Person → Which has a bigger acceleration: Earth/Person whilst jumping?

same time, different objects, same amount of force, opposite directions → Friction moves in this direction, but is opposite of this.

applied force → The Force of a surface acting on an object

friction → the resistance that one surface or object encounters when moving over another

250 N → A 10kg object is moving at 5 m/s². What is the net force acting on the object?

sum of all forces of an object → Action/Reaction pairs: What is the Reaction pair in a physics book on a table?

Newton → Which has a bigger acceleration: Earth/Person whilst jumping?

pulling earth up → There is a Force pulling us down and there is one doing this too.

perpendicular to surface → Friction opposes this.

Earth → Which has a bigger mass: Earth/Person whilst jumping?

static → This friction is resistive at rest (keep something from moving)

static and kinetic → Two types of friction

Physical Interaction → An objects resistance to change its motion

Fg = mg → Weight equation

Object will do what it does unless otherwise acted on → A Net Force is a....

gravitational force → When someone jumps up, this pulls them back down.

Newton's 3rd Law → An object in motion will stay in motion and an object at rest will stay at rest unless acted on by an outside force.
