Force and Motion

What are balanced forces?

• Forces that are equal in size and opposite in direction, resulting in no change in motion.

• Forces that are unequal in size and act in the same direction, causing acceleration.

• Forces that are equal in size and act in the same direction, resulting in increased speed.

• Forces that are opposite in direction but unequal in size, causing a change in motion.

What is inertia?

• The tendency of an object to resist changes in its state of motion.

• The force that causes an object to accelerate.

• The speed of an object in a straight line.

• The mass of an object multiplied by its velocity.

What is mass?

• The amount of matter in an object, which affects its inertia.

• The force exerted by gravity on an object.

• The volume of an object measured in cubic units.

• The speed at which an object moves.

What causes an object to move?

• Balanced forces

• Frictional forces

• Unbalanced forces

• Gravitational forces

What is the difference between speed and velocity?

• Speed is the distance traveled per unit of time, while velocity includes direction.

• Speed is always greater than velocity.

• Velocity is the total distance traveled regardless of direction.

• Speed and velocity are the same thing.

What is the role of gravity in motion?

• It pulls objects towards the center of the Earth, affecting their motion.

• It pushes objects away from the Earth, increasing their speed.

• It has no effect on the motion of objects in space.

• It only affects objects that are in free fall.

What does gravity do?

• It is the force that repels objects away from each other.

• It is the force that attracts objects towards each other.

• It is the force that keeps objects stationary.

• It is the force that makes objects float.

What happens to an object in free fall?

• It accelerates downwards due to gravity.

• It remains stationary in the air.

• It moves upwards at a constant speed.

• It experiences an increase in mass.

What is friction?

• A force that makes objects in motion speed up.

• An opposing force that makes objects in motion slow down.

• A force that has no effect on moving objects.

• A type of energy that causes movement.

What is the formula for calculating force?

• Force = mass + acceleration (F = m + a)

• Force = mass × acceleration (F = ma)

• Force = mass / acceleration (F = m / a)

• Force = mass - acceleration (F = m - a)
