What is "energy"
The capacity to do work.
Who is Isaac Newton?
Isaac Newton was a physicist and mathematician who developed the principles of modern physics, including the laws of motion.
What is "Inertia"?
a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
IS ENERGY CAPABLE OF BEING TRANSFERRED? IF SO, GIVE AN EXAMPLE OF HOW ENERGY IS TRANSFERRED FROM ONE OBJECT TO ANOTHER.
YES. THE CONSERVATION OF MOMENTUM. THE TIME MS. KEANE STACKED A BALL ON TOP OF A BASKETBALL AND DROPPED THEM FROM THE SAME HEIGHT. THE MOMENTUM WAS TRANSFERRED FROM THE BASKETBALL (THAT HIT THE FLOOR) TO THE SMALLER BALL.
What is "Kinetic" Energy?
The energy of motion
State Newtons 1st Law of Motion
An object as rest stays at rest unless acted on by an external force. An object in motion continues to travel with constant speed in a straight line unless acted on by an external force.
If a ball is pushed with a force along the floor, what forces are acting upon the ball? How does the energy of the ball change?
What do you think these 3 things have in common?
*Battery
*Food
*Ms Keane Standing on a desk.
ENERGY
What is "Potential Energy"?
The energy of position, or stored energy.
Newtons first Law of Motion is also known as...
The law of Inertia
YOU AND A FRIEND ARE ICE SKATING. YOU FACE EACH OTHER AND PUT YOUR PALMS TOGETHER. YOU BOTH EXERT A FORCE. WHICH DIRECTION DOES THE FORCE PUSH YOU? WHICH OF NEWTON'S LAWS DOES THIS SUPPORT?
Opposite direction. Newtons 3rd Law
WHAT IS MOMENTUM?
“MASS IN MOTION”. IF AN OBJECT HAS MASS AND IS MOVING, IT HAS MOMENTUM.
What is "Mechanical Energy"
Energy that is composed of both potential energy and kinetic energy.
State Newtons 2nd Law of Motion
The acceleration of an object is DIRECTLY PROPORTIONAL to the force acting on it.
DOES THE MASS OF AN OBJECT AFFECT THE OBJECTS MOTION? IF SO, WHY AND HOW? IF NOT WHY? EXPLAIN AND GIVE AN EXAMPLE.
Yes, If the mass of two objects are different, the one with greater mass will have greater momentum and force in motion.
THE FASTER YOU PUSH ME... THE FARTHER I GO... YOUR ADDING......
VELOCITY
What does the CONSERVATION OF ENERGY state?
A principle stating that the total energy of an isolated system remains constant regardless of changes within the system. Energy can neither be created nor destroyed.
State Newtons 3rd Law of Motion
When 2 bodies interact, the FORCE exerted by object “B” on object “A” is equal in magnitude and opposite in direction to the FORCE exerted by object “A”.
OBJECT “A” HAS A MASS OF 3 KG AND OBJECT “B” HAS A MASS OF 5 KG. OBJECT “A” AND “B” ARE MOVING AT A CONSTANT SPEED. WHICH OBJECT HAS MORE MOMENTUM? WHY?
Object B. The greater the mass, the greater the momentum and force the object will have in a collision.
IF SOMETHING IS BEING "FORCED" IN A DIRECTION, WHAT DOES VELOCITY MEASURE ?
THE SPEED OF SOMETHING IN A GIVEN DIRECTION
