12 Questions
Which of the following is an example of a force?
Gravity
Which of the following best describes what happens when two objects with the same mass collide?
It depends on how fast they are moving
Which of the following best describes what happens when an object is at rest?
There are no forces acting on it
An object at rest will remain at rest unless acted upon by an unbalanced force.
True
The force of gravity between two objects decreases as the distance between them increases.
True
Friction is a force that always opposes motion between two surfaces in contact.
True
What is Newton's first law of motion?
An object at rest will remain at rest unless acted upon by an unbalanced force.
What is the difference between balanced and unbalanced forces?
Balanced forces are equal in size and opposite in direction, while unbalanced forces are not equal and cause a change in motion.
How do forces affect motion?
Forces can cause a change in motion, such as speeding up, slowing down, or changing direction.
______ is the tendency of an object to resist a change in motion.
Inertia
Gravity is an example of a ______.
Force
An unbalanced force can cause an object to ______.
Accelerate
Study Notes
Forces and Their Effects
- Force is an influence that causes an object to undergo a specific change in motion or shape.
- Gravity and friction are examples of forces that affect motion between objects.
- An unbalanced force acts to change the motion of an object, while balanced forces do not result in a change.
Newton's Laws of Motion
- Newton's first law of motion states: An object at rest will remain at rest unless acted upon by an unbalanced force.
- This law emphasizes that motion will not change unless forces interact.
Collisions
- When two objects with the same mass collide, momentum is transferred, and they may change their velocity according to elastic or inelastic collision rules.
Rest and Motion
- An object at rest remains in that state unless an unbalanced force is applied.
- The concept of inertia describes the tendency of an object to resist changes in its state of motion.
Effect of Gravity and Distance
- The gravitational force between two objects decreases as the distance between them increases, indicating an inverse relationship.
Friction
- Friction is a force that opposes the movement between two surfaces in contact, enabling resistance against sliding.
Key Terms
- Inertia is the tendency of an object to resist changes in motion.
- Gravity is an attractive force that acts between two masses, influencing their motion based on distance and mass.
