|---|---|---|---|---|---|
| What is a force ? | show 🗑
|
||||
| show | newtons
🗑
|
||||
| show | friction, upthrust, air resistance
🗑
|
||||
| name non-contact forces | show 🗑
|
||||
| Define upthrust | show 🗑
|
||||
| Define gravity | show 🗑
|
||||
| what is friction? | show 🗑
|
||||
| show | air resistance is the opposite force to movement and air resistance is created by particles!
🗑
|
||||
| show | more particles
🗑
|
||||
| show | gravity
🗑
|
||||
| show | air resistance
🗑
|
||||
| show | air resistance
🗑
|
||||
| show | in water
🗑
|
||||
| show | gravity.
🗑
|
||||
| show | downwards
🗑
|
||||
| show | the weight will be the different because only the mass does not change but when you are in space your weight changes it becomes lighter.
🗑
|
||||
| Describe and explain what happens to air resistance as you move faster | show 🗑
|
||||
| show | it enable them to move through water with the least possible water resistance.
🗑
|
||||
| show | when the parachute opens the air resistance will become much greater which slows the person riding it
🗑
|
||||
| show | As his speed reduces the air resistance will become less and eventually the forces will be the same again.
🗑
|
||||
| When you jump out of a plane and you open your parachute, describe the forces on you and your speed after a few minutes opening it? | show 🗑
|
||||
| show | Weight is the force that pulls you down; mass is the Number of atoms in the body
🗑
|
||||
| show | The weight! The mass measures the number of atoms in a body. That will NOT change on the Moon: you stay the same mass!
🗑
|
||||
| show | Upthrust
🗑
|
||||
| What can you do to make a car go faster? | show 🗑
|
||||
| show | True
🗑
|
||||
| show | Forces are balanced when they are equal in SIZE but opposite in DIRECTION: the forces cancel each other out.
🗑
|
||||
| When are forces unbalanced? | show 🗑
|
||||
| show | The Earth
🗑
|
||||
| fill in the blank: if the forces on an object are balanced and the object is ............., then it will remain stationary | show 🗑
|
||||
| show | direction may change, or the object may slow down, or it may accelerate(go faster)
🗑
|
||||
| This person is pushing down on the chair with force of 650N. What other force is acting to make it balanced | show 🗑
|
||||
| In a tug of war, when one team is pulling with a force of 100 N to the left and the other 80 N to the right, what is the net force? | show 🗑
|
||||
| A car is moving at a constant speed and the thrust of the engine is 500N forward. How big is the friction? | show 🗑
|
||||
| show | because the car is moving FASTER, it means that the forces are UNbalanced. So friction is less than 700N backwards.
🗑
|
||||
| A car is slowing down (decelerating). Compare the SIZE of thrust of the engine and friction | show 🗑
|
||||
| show | Gravity, Push of the floor, Thrust of engine, Air resistance/friction
🗑
|
||||
| show | Gravity is the same size as Push of the floor. Thrust of engine, is the same size as Air resistance/friction
🗑
|
||||
| What are the 2 forces on a stationary car | show 🗑
|
||||
| show | Gravity and Push of the floor are the same SIZE
🗑
