S8P3 GMAS Review - Force and Motion

What is displacement?

• The length of the path a moving object travels.

• The length and direction of a straight line between two locations.

• The rate at which the position of an object changes in time.

• The rate at which an object changes its velocity.

If the distance between two towns is longer than the actual displacement, what could be the reason?

• The object moved in a straight line.

• The object moved back and forth between the two points.

• The object's velocity was zero.

• The object's speed was constant.

What does velocity measure?

• The length of a path that a moving object travels.

• The length and direction of a straight line between two locations.

• The rate at which the position of an object changes in time.

• The rate at which an object moves along a path.

How is speed different from velocity?

• Velocity considers the direction of movement, while speed does not.

• Speed can be negative, while velocity cannot.

• Speed considers the direction of movement, while velocity does not.

• Speed measures the rate of change of velocity.

What is acceleration?

• The rate at which an object's speed changes.

• The rate at which an object's displacement changes.

• The rate at which an object's velocity changes.

• The rate at which an object's distance changes.

• Gravitational force

• Applied force

What are balanced forces?

• Forces that cause an object to move at a constant speed.

• Forces that cause an object to change its direction.

• Forces that cause an object's velocity to change.

• Forces that act on an object but do not change the object's velocity.

What happens when unbalanced forces act on an object?

• The object's motion does not change.

• The object accelerates.

• The object disappears.

• The object becomes weightless.

What is friction?

• The force that increases motion between two surfaces.

• The force that exists between any two masses.

• The force that resists motion between two surfaces.

• The resistance to change in the state of motion of an object.

What is inertia?

• The force of attraction between two or more masses.

• The force that resists motion between two surfaces.

• The resistance to any change in the state of motion of a physical object.

• The acceleration due to unbalanced forces.
