What is a force?
A hug or handshake
A sound or light
A color or shape
A push or pull
List three examples of contact forces.
Inertia, momentum, velocity
Gravity, magnetism, electricity
Pressure, temperature, density
Friction, tension, normal force
Explain the difference between contact and non-contact forces.
Contact forces involve direct physical contact, while non-contact forces act at a distance.
Contact forces involve eye contact, while non-contact forces involve no eye contact.
Contact forces involve using a computer mouse, while non-contact forces involve using a touch screen.
Contact forces involve sending a text message, while non-contact forces involve making a phone call.
What are the four fundamental forces in nature?
Gravity, Electromagnetism, Weak Nuclear Force, Strong Nuclear Force
Velocity, Acceleration, Kinetic Energy, Potential Energy
Heat, Light, Sound, Electricity
Friction, Tension, Inertia, Momentum
Give an example of a non-contact force.
Friction force
Gravity force
Magnetic force
Tension force
Define gravitational force and provide an example.
The force of friction between two surfaces.
The force of attraction between two objects with mass.
The force of repulsion between two objects with mass.
The force of attraction between a magnet and a metal object.
Explain the concept of frictional force and give an example.
Frictional force is the force that causes an object to move faster
Frictional force is the force that causes an object to slow down
When you rub your hands together, the frictional force generates heat.
Frictional force is the force that causes an object to float
What is the unit of force in the SI system?
kilogram (kg)
second (s)
meter (m)
newton (N)
Describe the difference between balanced and unbalanced forces.
Balanced forces have unequal magnitude or are not opposite in direction, resulting in a change in motion.
Balanced forces have equal magnitude and opposite direction, resulting in no change in motion. Unbalanced forces have unequal magnitude or are not opposite in direction, resulting in a change in motion.
Unbalanced forces have equal magnitude and opposite direction, resulting in no change in motion.
Balanced forces have equal magnitude and same direction, resulting in no change in motion.
How does the direction of a force affect its effect on an object?
It has no effect on the object
It determines the direction and magnitude of the object's acceleration.
It changes the object's mass
It determines the color of the object
A net force acting on an object will cause it to:
Stay at rest
Move at a constant Velocity
Accelerate
Force is a vector quantity, therefore it has:
Magnitude only
Direction only
Magnitude and Direction
Balanced forces cause an object to:
Stay at rest
Remain in motion
Either stay at rest or remain motion
Accelerate
What does friction do to an object?
Enhances/Helps Motion
Opposes Motion
Net force on an object that is pushed 5N East and 15N West?
5N East
10N East
5N West
10N West
20N East
If there is a net force of 10N acting on a 5Kg object, what is the acceleration of the object
50 N`
50 m/s2
2N
2 m/s2
What is the net Force of a 5kg object that is acceleration at 10m/s2
50 N`
50 m/s2
2N
2 m/s2
If the mass of an object is halved, the weight of the object is
halved
doubled
depends on location
none of these
State which of Newton's Laws is applicable to the following scenario. A team of dogs attached to a sled will travel faster than a single dog attached to a sled.
Newtons 1st Law (Law of Inertia)
Newtons 2nd Law (F = ma)
Newtons 3rd Law (Action = Reaction)
___________ is an opposing force that makes objects in motion slow down.
force
speed
friction
mass
The girls in this picture represent ________ forces (or 2 objects in equilibrium).
How does the mass of an object affect it's motion?
It has no effect
The less the mass the less effect a force will have
The greater the mass the greater the effect a force will have
The greater the mass the less effect a force will have

100 N
220 N
52 N
2.20 N
