Newton's Laws
What scientist came up with the Laws of Motion?
Sir Isaac Newton
Give an example of a force.
Answers vary (extra 100 points if you said gravity)
The force exerted by magnets when they attract or repel each other.
Magnetism
An invisible force that pulls objects towards each other.
What tool can be used to find our way if we are lost in the woods?
Compass
Which law of motion states that an object stays still unless another force acts on it? It also states that an object will move unless another force stops it.
First
Which law of motion fits the following scenario?
A harder kick (greater force) will send the ball flying farther (higher acceleration).
2nd
A push or pull upon an object
Force
The change in position of an object.
Motion
What does the Earth’s magnetic field protect us from?
The sun's solar winds and radiation.
Which law of motion states that for every action, there is an equal and opposite reaction?
Third
Which law of motion fits the following scenario?
During swimming, the water pushes back on the swimmer as the swimmer pushes against it to move ahead.
3rd
The resistance that one surface or object encounters when moving over another.
Friction
The measure of how much matter makes up a physical object
Mass
The Earth's core creates what around the Earth?
A protective magnetic field around the earth.
Which of Newton’s Laws of motion states that the greater the mass of an object, the more force it will take to accelerate the object?
Second
Which law of motion fits the following scenario?
A kickball is not going to move unless you kick it.
1st
The tendency to resist changes in a state of motion.
Inertia
Forces that are not equal in magnitude and may or may not act in the same direction.
Unbalanced forces
The magnetic force of a material comes from the spinning of what atomic particle?
Electrons
What happens if you let an untied balloon go? Which law of motion applies to this situation?
3rd Law: When we let go of the end, the air rushes out and pushes against the air around the balloon to move it in the opposite direction.
What happens to the speed of a toy car if you push it really hard compared to pushing it gently? Which law of motion applies to this situation?
2nd Law: The toy car that I pushed really hard would go farther than the toy car that I pushed gently.
The rate of change of velocity or how fast an object or person speeds up.
Acceleration
What do some animals use to find the right direction when migrating?
The Earth's magnetic field
