Identify Forces
A force is a push or pull that can cause an object to move, stop, or change directions
What is force?
Balanced forces are equal in size and opposite directions, resulting in no change in motion.
What is a balanced force?
Are forces that are not equal in size and opposite in direction, resulting in a change in motion
What is unbalanced forces?
What is Newton's Third Law?
It is calculated by adding together all the forces acting on an object considering their directions.
How do you calculate net force?
Contact forces are forces that occur when two objects are physically touching each other.
What is a contact force?
What is give an example of balanced forces?
What is an example of unbalanced forces?
When you push against the wall, the wall pushes back with equal and opposite forces.
What is giving an example of the third law?
The formula for calculating force is F=ma, where F is force, m is mass, and a is acceleration.
What is the formula for calculating force?
Non-contact forces are forces that act at a distance, such as gravity or magnetic forces.
What are non-contact forces?
Balanced forces do not change the motion of an object; it remains at rest or moves at a constant speed.
How do balanced forces affect motion?
Cause objects to accelerate, decelerate or change direction.
How do unbalanced forces affect motion?
When one pair of forces acting on different objects that are equal in size but opposite forces.
How do action and reaction forces work?
It is indicated by arrows, where the length represents the magnitude and the arrowhead shows the direction
How do you identify direction in forces?
Friction is a force that opposes the motion of an object when it comes into contact with another surface.
What is friction?
It is the state in which all the forces acting on an object are balanced, resulting in no net forces.
What is equilibrium?
Acceleration in the rate of change of velocity of an object, caused by unbalanced forces.
What is acceleration?
Rocket propulsion is a real world application, where the action of gases expelled downwards produces an upward force on the rocket.
What is a real-world application of the third law?
Mass is the amount of matter in an object, while weight is the gravitational force acting on the mass.
What is the difference between mass and weight?
Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the earth.
What is gravity?
When forces are balanced, the object does not accelerate; it either stays at rest or continues to move at a constant velocity.
What happens when forces are balanced?
Net forcesis calculated by adding all the forces acting on an object, taking into account for the direction.
How is net force calculated?
What is explaining momentum?
How do you calculate weight?
