Weight v mass
The amount of matter in an object
What is MASS?
Speed in a given direction.
What is velocity?
A ball pushed to the right with 5N of force & has 2N of friction acting on it has this net force. (include direction)
A box is moved from the bottom shelf to the top. This type of energy is increased.
What is potential?
A person holds a heavy book over their head. This is the amount of work they are doing.
What is 0 work?
Weight is dependent on this, which various on different planets
What is gravity?
What is speed?
An object at rest will remain at rest until this type of force is applied to it.
What is an unbalanced force?
The place on a roller coaster where the kinetic energy is the greatest.
What is the bottom of the steepest hill?
A hammer pulling a nail out of a board is an example of this type of simple machine.
What is a lever?
When going to Jupiter, this will happen to your weight.
What is increase?
If a car slows down, speeds up or changes direction it is doing this.
What is accelerating?
When a car crashes into a wall with 100N of force, the wall exerts this amount of force back on the car?
What is 100N of force?
Kinetic energy is most greatly influenced by this variable.
What is velocity/speed?
The tendency of an object to resist changes in motion is called this.
What is inertia?
When going to the moon this will NOT change.
What is your mass?
A flat, horizontal line on a distance vs time graph (see teacher image) means this.
What is the object is NOT moving?
If the same 4N force is applied to both a 50kg box and a 10kg box, this box will have a greater acceleration.
What is the 10kg box?
Friction converts mechanical energy into this form of energy.
What is thermal?
What is the force?
The acceleration of gravity here on Earth.
What is 9.8 m/s2?
A car goes from 30mph to 50mph in 2 seconds, this is its acceleration rate.
What is 10 m/s2?
The amount of force that is applied to a 50kg ball in order for it to accelerate at a rate of 2 m/s2.
What is 100N of force?
A ball with a mass of 2kg and moves 3 m/s has this much kinetic energy.
What is 9J?
This law of motion states that an object at rest will remain at rest unless an unbalanced force is applied.
What is Newton's 1st law?
