Newton's first law of motion states that __________.
an object will remain at rest or keep moving with a constant velocity unless a force acts on it
acceleration is calculated by dividing the force exerted on an object by the mass of the object
when a force acts on an object, its acceleration is in the same direction as the force
when a force is applied to an object, there is an equal force applied by the object in the opposite direction
A ball is thrown straight up in the air. According to Newton's first law of motion, what is the reason for the ball falling back to Earth?
A force has acted on it.
The change in the ball's acceleration is proportional to the force acting on it.
The ball exerts a force on the air surrounding it.
It is accelerating in the same direction as Earth's gravitational force on it.
Which measures an object's tendency to resist changing its motion?
gravity
acceleration
mass
inertia
What happens when unbalanced forces act on an object?
The object accelerates.
The net force is zero.
The object speeds up.
Friction becomes greater than the net force.
Newton's second law of motion states that __________.
an object will remain at rest or keep moving in a straight line with constant speed unless a force acts on it
when a force is applied on an object, there is an equal force applied by the object in the opposite direction
the force on an object can be found by dividing its mass by its acceleration
acceleration is calculated by dividing the force exerted on an object by the mass of the object
A change in motion is described by __________.
inertia
acceleration
net force
speed
Newton's third law of motion states that __________.
an object will remain at rest or keep moving in a straight line with constant speed unless a force acts on it
when a force is applied on an object, there is an equal force applied by the object in the opposite direction
acceleration is calculated by dividing the force exerted on an object by the mass of the object
the force on an object can be found by dividing its mass by its acceleration
