Forces 1
It is a push or a pull.
FORCE
A force exerted by the Earth's gravity on every object that has mass.
weight
The acceleration of free-falling objects due to gravity.
10 m/s2
It is equal to 1 N.
1 kg m/s2
This does not change for an object even if the gravity on it changes.
mass
Complete the statement. "A zero net force on an object at rest will make the object _______________."
remain at rest
The attractive force exerted by the Earth on any object.
gravity
The force applied by a rocket's engine to lift it up.
Lift-off or applied force
A net force acting on an object will cause it to ____________.
accelerate
A force that opposes the motion of an object.
friction
The net force on an object due to the following forces; 20 N to the right, 5 N to the left and another 8 N to the right.
23 N, to the right
The acceleration of an object if the net force acting on it is zero.
zero
It refers to the sum of all the forces acting on an object.
net force
It tells how strong a force is exerted on an object.
acceleration
The constant velocity at which a falling object will fall when the weight and the air resistance are balanced.
terminal velocity
