Calculating weight
Forces in action
100
The term for a push, pull, or twist.
A force
100
True or False: The forces are unbalanced.
False
100
The force that occurs when there external push or pull exerted on an object by a person or another object.
An applied force
100
A person weighs 50 kg. Estimate their weight.
50kg x 10= 500 N.
100
The ways a force can affect an object.
start moving
stop moving
speed up
slow down
change direction
change shape
200
The term for the type of force that can be exerted without contact.
A non contact force
200
True or False: The forces are balanced.
False
200
The upward force a fluid (liquid or gas) exerts on a submerged or floating object, opposing gravity.
Buoyancy
200
The formula for calculating the weight force of an object.
Weight= mass x g (~10)
200
The type of force acting in this image.
Tension.
300
The term for how much matter an object contains.
The mass
300
True or false: The forces are unbalanced.
True
300
The fundamental, non-contact force of attraction or repulsion acting on charged particles in motion or materials within a magnetic field.
Magnetism
300
What is the number for the acceleration due to gravity? Hint: it is measured in m/s^2
9.8 m/s^s (~10)
300
The way I adjust the arrows in a diagram to show a larger force.
Longer the arrow
400
The term for when the net force acting on an object is not zero, meaning opposing forces are unequal in magnitude
An unbalanced force
400
True or false: the forces are balanced.
False
400
The invisible, attractive force existing between any two objects with mass
Gravitational force
400
If someone weighs 60 kg on Earth and they travel to the moon where gravitational strength is 6x weaker, what is the weight force on that person?
60kg x 10= 600 N/6= 100 N
400
If two balls are the same size but different masses, will a force affect them the same?
No. The larger mass will be less affected.
500
The term for the force of gravity acting on an object.
The weight (gravitational force)
500
True or false: The force is unbalanced.
True
500
The powerful, non-contact, attractive or repulsive force between charged particles
Electrostatic force
500
If someone weighs 50 kg on Earth and they travel to the Mars where gravitational strength is 3x stronger, what is the weight force on that person?
50kg x 10= 500 N x 3= 1500 N
500
The reason why an apple on a desk is not moving. Are the forces balanced or unbalanced?
Forces are balanced. The upward normal force and downward weight.
