Vocabulary
anything that takes up space and has mass
What is matter?
A bird pushes air down with its wings, and the air pushes back up, lifting the bird.
What is Newton's 3rd Law of Motion?
the rubbing of two surfaces that are touching, causes an object to slow down
What is friction?
A force of 20 N acts upon a 5 kg block. Calculate the acceleration of the object.
What is 4m/s2 ?
How much time will it take for a bug to travel 5 meters across the floor if it is traveling at 1 m/s?
What is 5 seconds?
the amount of matter in an object, measured in kilograms
mass
For every action, there is an equal and opposite reaction.
What is Newton's 3rd Law of Motion?
how far an object moves
What is distance?
A force of 30 N acts upon a 6 kg block. Calculate the acceleration of the object.
What is 5 m/s2?
A sprinter runs 100 meters at a speed of 10 meters per second. How long does it take to finish the race?
when an object changes position, moves
What is motion
an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force (also known as the law of inertia)
What is Newton's First Law of Motion?
17th Century scientist who formulated the concept of gravity and the laws of motion
Who is Isaac Newton?
A box with a mass of 4 kg is pushed with a force of 16 N. Find its acceleration.
What is 4 m/s2?
A cheetah runs 300 meters at a speed of 25 meters per second. How many seconds does it take?
an indicator that orients you, the place from where you measure or witness an event, a specific place
an object's acceleration depends on its mass and the force acting on it (force = mass • acceleration; F = m • a)
What is Newton's Second Law of Motion?
the force of attraction that two objects exert on each other
What is gravity?
A force of 75 N acts upon a 15 kg object. Calculate the acceleration of the object.
What is 5 m/s2 ?
A baseball is thrown at a speed of 30 meters per second and travels 90 meters before being caught. How many seconds does it take?
What is 3 seconds?
the amount of change in an objects position from the starting point to the ending point, distance and direction
17th Century scientist who formulated the concept of gravity and the laws of motion
Who is Isaac Newton?
the resistance to change in motion; the tendency of an object at rest to remain at rest and an object in motion to remain in motion
What is inertia?
