Physics Review

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

Define average speed.

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

Front

Explain the concept of friction.

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

What does a distance-time graph represent?

Back

A distance-time graph shows how the distance traveled by an object changes over time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What happens to an object's motion when a net force acts on it?

Back

The object will accelerate in the direction of the net force.

Front

Define inertia.

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass x Gravity.
