Forces and Motion

What is gravitational force?

• Gravitational force is the repulsion between two masses.

• Gravitational force is the attraction between two masses.

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

• Gravitational force is the force that opposes motion.

What is the effect of unbalanced forces on an object?

• Unbalanced forces cause an object to remain at rest.

• Unbalanced forces cause an object to accelerate in the direction of the net force.

• Unbalanced forces have no effect on an object's motion.

• Unbalanced forces cause an object to move at a constant speed.

What is the definition of velocity?

• Velocity is the speed of an object in a specific direction.

• Velocity is the distance traveled by an object over time.

• Velocity is the rate of change of an object's position.

• Velocity is the maximum speed an object can achieve.

What is Newton's Second Law of Motion?

• F = ma (Force equals mass times acceleration)

• F = mv^2 (Force equals mass times velocity squared)

• F = m/g (Force equals mass divided by gravity)

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

What is the effect of balanced forces on an object?

• Balanced forces cause the object to accelerate.

• Balanced forces change the direction of the object.

• Balanced forces do not change the motion of an object.

• Balanced forces increase the object's speed.

What did Isaac Newton's mother want him to be?

• A farmer.

• A scientist.

• A teacher.

• A merchant.

What is inertia?

• The force that causes an object to move in a circular path.

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

• The speed at which an object travels in a straight line.

• The energy stored in an object due to its position.

What is the relationship between mass and acceleration in Newton's Second Law?

• Mass and acceleration are directly proportional when force is constant.

• Mass and acceleration are inversely proportional when force is constant.

• Mass and acceleration are unrelated when force is constant.

• Mass and acceleration are equal when force is constant.

What is the formula for calculating momentum?

• Momentum = Mass + Velocity

• Momentum = Mass x Velocity

• Momentum = Mass / Velocity

• Momentum = Mass - Velocity

What formula is used to find speed?

• Speed = Distance + Time

• Speed = Distance - Time

• Speed = Distance / Time

• Speed = Distance * Time
