Forces and Motion

What is speed?

• Speed is the distance traveled by an object in a given amount of time.

• Speed is the rate at which an object changes its position.

• Speed is the total distance covered by an object regardless of time.

• Speed is the measure of how fast an object can accelerate.

What is velocity?

• The speed of an object in a specific direction.

• The distance traveled by an object over time.

• The rate of change of an object's position.

• The total amount of energy an object has.

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 friction?

• A force that accelerates an object in motion.

• A force that opposes the motion of an object, caused by the contact between two surfaces.

• A type of energy that is lost during motion.

• A force that increases the speed of an object.

What is net force?

• Net force is the total force acting on an object after all opposing forces are subtracted.

• Net force is the overall force on an object when all the individual forces acting on it are added together.

• Net force is the force that is applied to an object to keep it in motion.

• Net force is the force that acts on an object due to gravity alone.

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 measure of an object's mass.

• Inertia is the speed of an object in motion.

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 gravitational force?

• Gravitational force is the attraction between two objects due to their mass.

• Gravitational force is the repulsion between two objects due to their mass.

• Gravitational force is the force that keeps objects in motion.

• Gravitational force is the energy produced by an object's mass.

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 energy an object possesses due to its position.

• Momentum is the rate of change of an object's mass.

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 in motion stays in motion 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.
