Newtons Laws 1
This is a measure of the change in the velocity or direction of a moving object.
acceleration
Explain the forces on a box sitting on the gorund.
Gravitational, normal
The SI unit of force is this.
Newton
This states that an object’s motion will not change unless an unbalanced force acts on the object.
Newton's First Law
The SI unit of acceleration is this.
According to Newton’s Second Law, increasing the force applied to a mass has this result.
Increases acceleration of the object
Explain the forces on a box being pushed to the right
Gravitational, normal, frictional, applied
Newton's third law states...
Any action has an equal and opposite reaction.
The type of force exerted by a solid, stable object
Normal Force
Mass has this SI unit.
kg, kilogram
These two laws allow us to generally predict who is going to win a tug of war match.
Newton’s First and Second Laws
A bowling ball collides with a set of bowling pins (at rest) with a force of 15N. What is the force the pins exert on the bowling ball.
15N
A car and a train are going the same speed. The car is easier to stop because of this.
less mass and less inertia
This occurs whenever an object is acted upon by an unbalanced force.
acceleration, change in motion
This is required to overcome an object’s inertia.
An unbalanced force, any net force
An object at rest has this velocity.
Zero
This property of matter increases with its mass.
inertia
Two objects collide going the same speed. Their rebound is different. What can be said about their mass?
Their mass is not equal.
The force pushing back up on an object that is resting on the ground
Normal force
Spring A has 150N of potential Elastic Energy. Spring B has 345N of potential Elastic Energy. Which spring would be able to propel a metal ball farther?
Spring B, it has more potential energy
Newton’s Second Law can be summarized using this equation.
f=ma
Explain the forces on a skier going down hill
Air resistance, gravitational, normal, frictional
Two objects collide going the same speed. Their rebound is equal. What can be said about the mass of the two objects?
Mass is equal
If a ball is moving with a force 49 Newtons and has an acceleration of 7 m/s2, what is the ball's mass?
7 kg
Haters gonna hate but which quarterback should be considered the all time GOAT?
