Force Flashcards

Force

TermDefinition
What is force force can cause a moving object to move quickly, to move more slowly or to change direction in which it is moving.
what is the unit of force newtons
what is weight is the force pulling an object towards the center of the earth
what is mass is the amount of matter in an object
what is a moment of force Moment of Force simply refers to a force causing something to spin.
lever formula Smaller force x larger distance = larger force x smaller distance
how to calculate pressure pressure = force over area
units for pressure 1. N/cm2 or N cm2 2. N/m2 or N m2 3. Pascal(Pa), which is another way of saying N/m2
what is the meaning of 'work' Work is done if a force results in an object moving a distance
unit of work Joules
formula of 'Work' Work=force x distance
what is the meaning of 'power' power = work + done over time taken
what are balanced forces If the force of an object is balanced the object remains at constant velocity
what are unbalanced forces If the forces on an object are unbalanced the object accelerates
what is extension plotted against force it is a graph that drawn on a graph page
what are examples of force Gravitational force, Magnetic, electrical force
what is friction the resistance that one surface or object encounters when moving over another.
what is a gravitational force a gravitational force is the force that keeps the earth circling the sun
what is an electrical force binds atoms together example ionic bonding
what is a magnetic force An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil.
how can you prevent bad friction rub vaseline or oil in places like underarms
what is a frictional force allows cars to turn a corner
What is the law of an elastic body is directly proportionate to the force causing the extension Hookes Law
What is Newton's first law An object at rest tends to stay at rest and an object in motion tends to stay in motion tends to stay in motion unless acted upon by an unbalanced force
What is Newtons Second law Force equals times acceleration F = ma Acceleration: a measurement of how quickly an object is changing speed.
What is Newtons Third law For every reaction there is an equal and opposite reaction

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
