Forces and Motion

What is an unbalanced force?

• An unbalanced force is when the resultant force acting on a body is not equal to zero, causing the body to move or change its direction, size, or shape.

• An unbalanced force is a force that is equal in magnitude and opposite in direction to another force, resulting in no movement.

• An unbalanced force is a force that acts on an object at rest, causing it to remain stationary.

• An unbalanced force is a force that causes an object to accelerate in a straight line without changing its speed.

What is Newton's First Law of Motion?

• An object at rest will stay at rest, and an object in motion will stay in motion at a constant speed and in a straight line unless acted upon by an unbalanced force.

• An object will accelerate in the direction of the net force acting on it.

• For every action, there is an equal and opposite reaction.

• An object in motion will eventually come to a stop due to friction.

What is a balanced force?

• A force that causes an object to accelerate in the direction of the force.

• A force that occurs when the forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

• A force that is always greater than the opposing force, causing movement.

• A force that acts only on stationary objects, preventing them from moving.

What is momentum?

• Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.

• Momentum is the force applied to an object over time.

• Momentum is the speed of an object in a given direction.

• Momentum is the total energy of an object in motion.

What is Newton's Third Law of Motion?

• For every action, there is an equal and opposite reaction.

• An object in motion stays in motion unless acted upon by an external force.

• The force of gravity is proportional to the mass of the objects involved.

• Energy cannot be created or destroyed, only transformed.

What is gravitational force?

• The force that keeps us grounded on Earth.

• The attraction between two objects due to their mass.

• A force that repels objects away from each other.

• The force that causes objects to float in space.

What is Newton's Second Law of Motion?

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

• An object at rest will remain at rest unless acted upon by an external force.

• The force acting on an object is equal to the mass of the object multiplied by its velocity (F=mv).

• For every action, there is an equal and opposite reaction.

What is acceleration?

• Acceleration is the rate at which velocity changes.

• Acceleration is the speed of an object in a straight line.

• Acceleration is the distance covered by an object in a given time.

• Acceleration is the force applied to an object.

What is inertia?

• Inertia is the tendency of an object to resist changes in its state of motion.

• Inertia is the force that causes an object to accelerate.

• Inertia is the mass of an object multiplied by its velocity.

• Inertia is the energy possessed by an object due to its motion.

What is a variable in science?

• A constant that does not change.

• A letter or symbol that represents a number that can change.

• A fixed value used in calculations.

• An equation that describes a relationship.
