Question
What is Newton’s first law and how does it relate to rocket launch?
Answer
Newton’s first law states that an object at rest will stay at rest unless acted upon by an unbalanced force. In the case of a rocket launch, the rocket stays still until the unbalanced force of thrust is greater than the forces of gravity and drag, causing it to accelerate upwards.
Question
What is the difference between balanced and unbalanced forces during a rocket launch?
Answer
Balanced forces are equal and opposite, canceling each other out to keep the rocket at rest. Unbalanced forces, on the other hand, cause the rocket to accelerate upwards by pushing it in one direction more than another.
Question
What is the resultant force during a rocket launch and how does it affect the rocket?
Answer
The resultant force is the sum of all forces acting on the rocket, including thrust, weight, and drag. If the resultant force is upwards, the rocket will accelerate upwards. If the resultant force is downwards, the rocket will slow down and fall back to Earth.
According to Newton's first law, an object at rest will remain at rest unless acted on by an ______ force.
unbalanced
For an object to start moving, there needs to be an ______ force.
unbalanced
A rocket launches when the force of ______ pushing it upwards is greater than the weight force due to gravity downwards.
thrust
An object at rest will remain at rest unless acted on by an unbalanced force
True
Forces pulling and pushing a rocket downwards are gravity and drag
True
A rocket will continue to speed up as long as the force of thrust pushing it upwards is greater than the weight force due to gravity downwards
True
Study Notes
Newton's First Law
- An object at rest will remain at rest unless acted on by an unbalanced force.
- An object will continue to accelerate if there is a net force acting on it.
